Each job j comes with a resource requirement r_j \\in {0,1}. The job can be processed at full speed if granted its full resource requirement. If receiving only an x-portion of r_j, it is processed at an x-fraction of the full speed. Our goal is to find a resource assignment that minimizes the makespan (i.e., the latest completion time). Variants of such problems, relating the resource assignment of jobs to their \\emph{processing speeds}, have been studied under the term discrete-continuous scheduling. Known results are either very pessimistic or heuristic in nature.In this paper, we suggest and analyze a slightly simplified model. It focuses on the assignment of shared continuous resources to the processors. The job assignment to processors and the ordering of the jobs have already been fixed. It is shown that, even for unit size jobs, finding an optimal solution is NP-hard if the number of processors is part of the input. Positive results for unit size jobs include an efficient optimal algorithm for 2 processors. Moreover, we prove that balanced schedules yield a 2-1/m-approximation for a fixed number of processors. Such schedules are computed by our GreedyBalance algorithm, for which the bound is tight."}],"page":"128-137","year":"2014","type":"conference","citation":{"short":"A. Brinkmann, P. Kling, F.

This allocation can be computed by uniformly raising the bandwidths of all users without violating capacity constraints. We consider an extension of these allocations by raising the bandwidth with arbitrary and not necessarily uniform time-depending velocities (allocation rates). These allocations are used in a game-theoretic context for routing choices, which we formalize in progressive filling games (PFGs).We present a variety of results for equilibria in PFGs. We show that these games possess pure Nash and strong equilibria. While computation in general is NP-hard, there are polynomial-time algorithms for prominent classes of Max-Min-Fair Games (MMFG), including the case when all users have the same source-destination pair. We characterize prices of anarchy and stability for pure Nash and strong equilibria in PFGs and MMFGs when players have different or the same source-destination pairs. In addition, we show that when a designer can adjust allocation rates, it is possible to design games with optimal strong equilibria. Some initial results on polynomial-time algorithms in this direction are also derived.

Each has individual qualities and hence the performance of a network node results from the networks' interplay.We introduce a new game theoretic model capturing the interplay between a high-speed backbone network and a low-speed general purpose network. In our model, n nodes are connected by a static network and each node can decide individually to become a gateway node. A gateway node pays a fixed price for its connection to the high-speed network, but can utilize the high-speed network to gain communication distance 0 to all other gateways. Communication distances in the low-speed network are given by the hop distances. The effective communication distance between any two nodes then is given by the shortest path, which is possibly improved by using gateways as shortcuts.Every node v has the objective to minimize its communication costs, given by the sum (SUM-game) or maximum (MAX-game) of the effective communication distances from v to all other nodes plus a fixed price \\alpha > 0, if it decides to be a gateway. For both games and different ranges of \\alpha, we study the existence of equilibria, the price of anarchy, and convergence properties of best-response dynamics."}],"ddc":["040"],"user_id":"15415","author":[{"last_name":"Abshoff","full_name":"Abshoff, Sebastian","first_name":"Sebastian"},{"full_name":"Cord-Landwehr, Andreas","first_name":"Andreas","last_name":"Cord-Landwehr"},{"first_name":"Daniel","full_name":"Jung, Daniel","last_name":"Jung","id":"37827"},{"id":"40384","last_name":"Skopalik","full_name":"Skopalik, Alexander","first_name":"Alexander"}],"publication":"Proceedings of the 7th International Symposium on Algorithmic Game Theory (SAGT)","file_date_updated":"2018-03-16T11:24:40Z","file":[{"file_name":"452-title_multilevel-sagt.pdf","date_created":"2018-03-16T11:24:40Z","access_level":"closed","file_size":84783,"creator":"florida","file_id":"1343","content_type":"application/pdf","date_updated":"2018-03-16T11:24:40Z","success":1,"relation":"main_file"}],"has_accepted_license":"1","status":"public","date_created":"2017-10-17T12:42:20Z","_id":"452","citation":{"ieee":"S.

We consider both games with non-decreasing cost functions as well as games with non-increasing utility functions. We show that the value of the potential function $\\Phi(\\sf s)$ of any outcome $\\sf s$ of a congestion game approximates the optimum potential value $\\Phi(\\sf s^*)$ by a factor $\\Psi_{\\mathcal{F}}$ which only depends on the set of cost/utility functions $\\mathcal{F}$, and an additive term which is bounded by the sum of the total possible improvements of the players in the outcome $\\sf s$. The significance of this result is twofold. On the one hand it provides \\emph{Price-of-Anarchy}-like results with respect to the potential function. On the other hand, we show that these approximations can be used to compute $(1+\\varepsilon)\\cdot\\Psi_{\\mathcal{F}}$-approximate pure Nash equilibria for congestion games with non-decreasing cost functions. For the special case of polynomial cost functions, this significantly improves the guarantees from Caragiannis et al. [FOCS 2011].

HSkip+ has the same topology as the Skip+ graph proposed by Jacob et al. [PODC 2009] but its self-stabilization mechanism significantly outperforms the self-stabilization mechanism proposed for Skip+. Also, the nodes are now ordered according to their bandwidths and not according to their identifiers. Various other solutions have already been proposed for overlay networks with heterogeneous bandwidths, but they are not self-stabilizing. In addition to HSkip+ being self-stabilizing, its performance is on par with the best previous bounds on the time and work for joining or leaving a network of peers of logarithmic diameter and degree and arbitrary bandwidths. Also, the dilation and congestion for routing messages is on par with the best previous bounds for such networks, so that HSkip+ combines the advantages of both worlds. Our theoretical investigations are backed by simulations demonstrating that HSkip+ is indeed performing much better than Skip+ and working correctly under high churn rates.","lang":"eng"}],"doi":"10.1109/P2P.2014.6934300","date_updated":"2022-01-06T07:00:20Z","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"5","name":"SFB 901 - Subproject A1"}],"department":[{"_id":"79"},{"_id":"63"},{"_id":"541"}],"title":"HSkip+: A Self-Stabilizing Overlay Network for Nodes with Heterogeneous Bandwidths","external_id":{"arxiv":["1408.0395"]}},{"user_id":"477","ddc":["040"],"title":"Energy-efficient Scheduling Algorithms","abstract":[{"text":"In meiner Dissertation besch{\\\"a}ftige ich mich mit dem Entwurf und der Analyse energieeffizienter Schedulingalgorithmen, insbesondere f{\\\"u}r sogenannte Speed-Scaling Modelle. Diese stellen das theoretische Pendant von Techniken wie AMDs PowerNOW! und Intels SpeedStep dar, welche es erlauben die Geschwindigkeit von Prozessoren zur Laufzeit an die derzeitigen Bedingungen anzupassen. Theoretische Untersuchungen solcher Modelle sind auf eine Arbeit von Yao, Demers und Shenker (FOCS'95) zur{\\\"u}ckzuf{\\\"u}hren. Hier kombinieren die Autoren klassisches Deadline-Scheduling mit einem Prozessor der Speed-Scaling beherrscht. Es gilt Jobs verschiedener Gr{\\\"o}ße fristgerecht abzuarbeiten und die dabei verwendete Energie zu minimieren. Der Energieverbrauch des Prozessors wird durch eine konvexe Funktion $\\POW\\colon\\R_{\\geq0}\\to\\R_{\\geq0}$ modelliert, welche die Geschwindigkeit auf den Energieverbrauch abbildet.Meine Dissertation betrachtet verschiedene Varianten des urspr{\\\"u}nglichen Speed-Scaling Modells. Forschungsrelevante Ergebnisse sind in den Kapiteln 3 bis 6 zu finden und erstrecken sich {\\\"u}ber die im Folgenden beschriebenen Aspekte:- Kapitel 3 und 4 betrachten verschiedene \\emph{Price-Collecting} Varianten des Originalproblems. Hier d{\\\"u}rfen einzelne Deadlines verfehlt werden, sofern eine jobabh{\\\"a}ngige Strafe gezahlt wird. Ich entwerfe insbesondere Online-Algorithmen mit einer beweisbar guten Competitiveness. Dabei liefern meine Ergebnisse substantielle Verbesserungen bestehender Arbeiten und erweitern diese unter Anderem auf Szenarien mit mehreren Prozessoren.- In Kapitel 5 wird statt des klassischen Deadline-Schedulings eine Linearkombination der durchschnittlichen Antwortzeit und des Energieverbrauchs betrachtet. Die Frage, ob dieses Problem NP-schwer ist, stellt eine der zentralen Forschungsfragen in diesem Gebiet dar. F{\\\"u}r eine relaxierte Form dieser Frage entwerfe ich einen effizienter Algorithmus und beweise seine Optimalit{\\\"a}t.- Das letzte Kapitel betrachtet ein Modell, welches – auf den ersten Blick – nicht direkt zur Speed-Scaling Literatur z{\\\"a}hlt. Hier geht es stattdessen um ein allgemeines Resource-Constrained Scheduling, in dem sich die Prozessoren zusammen eine gemeinsame, beliebig aufteilbare Ressource teilen. Ich untersuche die Komplexit{\\\"a}t des Problems und entwerfe verschiedene Approximationsalgorithmen.","lang":"eng"}],"date_created":"2017-10-17T12:42:15Z","project":[{"name":"SFB 901","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2"},{"_id":"4","name":"SFB 901 - Project Area C"}],"has_accepted_license":"1","status":"public","file":[{"creator":"florida","file_id":"1356","file_size":792106,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-16T11:31:29Z","date_created":"2018-03-16T11:31:29Z","file_name":"431-Peter_Kling_PhDThesis_01.pdf","access_level":"closed"}],"file_date_updated":"2018-03-16T11:31:29Z","department":[{"_id":"63"}],"publisher":"Universität Paderborn","author":[{"last_name":"Kling","full_name":"Kling, Peter","first_name":"Peter"}],"date_updated":"2022-01-06T07:00:52Z","_id":"431","supervisor":[{"first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide","id":"15523"}],"citation":{"short":"P.

Für solch heterogene Daten existiert kein Algorithmus, der die Gesamtheit der Daten sowohl schnell als auch mit guter Qualität darstellen kann. Die Auswahl der richtigen Algorithmen für einzelne Szenenteile durch einen Experten ist zeitintensiv und in vielen Visualisierungssystemen nicht umzusetzen. Um dieses Problem zu lösen, setzt das hier vorgestellte Multi-Algorithmen-Rendering verschiedene Renderingalgorithmen gleichzeitig ein, um eine virtuelle 3-D-Szene darzustellen. Das Verfahren unterteilt die Szene dafür in einem Vorverarbeitungsschritt automatisch in geeignete Teilregionen und bestimmt deren Eigenschaften. Diese Daten werden zur Laufzeit dazu genutzt, um ständig für den aktuellen Standpunkt des Betrachters eine Abschätzung der Qualität und Laufzeit der zur Auswahl stehenden Renderingalgorithmen zu berechnen. Durch die Lösung eines Optimierungsproblems kann so bei vorgegebener Bildrate durch die passende Zuordnung der Algorithmen zu den Regionen die Bildqualität optimiert werden – bei automatischer Anpassung an die Leistungsfähigkeit der eingesetzten Hardware. In einer experimentellen Evaluierung vergleichen wir die Laufzeit und Bildqualität des Verfahrens mit denen verbreiteter Standardrenderingverfahren."}],"place":"Paderborn","date_created":"2020-07-29T08:55:43Z","status":"public","volume":311,"department":[{"_id":"63"}],"publication":"11.

In order to optimize the selection of flows transmitted to the gateway, D-UFP takes into account possible dependencies between flows. We show that D-UFP is more difficult than NP-hard problems for which no good approximation is known. Then, we address two special cases of this problem: the case where all the sensors have a shared channel and the case where the sensors form a mesh and route to the gateway over a spanning tree.","lang":"eng"}],"extern":"1"},{"title":"Token Dissemination in Geometric Dynamic Networks","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt A1","_id":"5"},{"_id":"2","name":"SFB 901 - Project Area A"}],"department":[{"_id":"63"}],"doi":"10.1007/978-3-642-45346-5_3","date_updated":"2022-01-06T07:01:21Z","series_title":"Lecture Notes in Computer Science","ddc":["040"],"user_id":"15504","abstract":[{"text":"We consider the k-token dissemination problem, where k initially arbitrarily distributed tokens have to be disseminated to all nodes in a dynamic network (as introduced by Kuhn et al., STOC 2010).

Our worst-case adversary is allowed to move the nodes on the plane, but the maximum velocity v_max of each node is limited and the graph must be connected in each round. For this model, we provide almost tight lower and upper bounds for k-token dissemination if nodes are restricted to send only one token per round. It turns out that the maximum velocity v_max is a meaningful parameter to characterize dynamics in our model.","lang":"eng"}],"date_created":"2017-10-17T12:42:25Z","has_accepted_license":"1","status":"public","file_date_updated":"2018-03-15T14:06:38Z","publication":"Algorithms for Sensor Systems - 9th International Symposium on Algorithms and Experiments for Sensor Systems, Wireless Networks and Distributed Robotics, {ALGOSENSORS} 2013, Sophia Antipolis, France, September 5-6, 2013, Revised Selected Papers","author":[{"last_name":"Abshoff","first_name":"Sebastian","full_name":"Abshoff, Sebastian"},{"last_name":"Benter","first_name":"Markus","full_name":"Benter, Markus"},{"first_name":"Andreas","full_name":"Cord-Landwehr, Andreas","last_name":"Cord-Landwehr"},{"last_name":"Malatyali","full_name":"Malatyali, Manuel","first_name":"Manuel"},{"full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm","id":"15523","last_name":"Meyer auf der Heide"}],"file":[{"access_level":"closed","date_created":"2018-03-15T14:06:38Z","file_name":"477-geometric-dynamic-networks_01.pdf","relation":"main_file","success":1,"date_updated":"2018-03-15T14:06:38Z","content_type":"application/pdf","file_id":"1325","creator":"florida","file_size":193169}],"_id":"477","page":"22-34","type":"conference","year":"2013","citation":{"ieee":"S.

Dies ist ein Optimierungsproblem, bei dem festgelegt werden muss an welchen Positionen Ressourcen zur Verf{\\\"u}gung gestellt werden, so dass diese von Nutzern gut erreicht werden k{\\\"o}nnen. Es sollen dabei Kosten minimiert werden, die zum einen durch Bereitstellung von Ressourcen und zum anderen durch Verbindungskosten zwischen Nutzern und Ressourcen entstehen. Die Schwierigkeit des Problems liegt darin, dass man einerseits m{\\\"o}glichst wenige Ressourcen zur Verf{\\\"u}gung stellen m{\\\"o}chte, andererseits daf{\\\"u}r sorgen muss, dass sich Nutzer nicht all zu weit weg von Ressourcen befinden. Dies w{\\\"u}rde n{\\\"a}mlich hohe Verbindungskosten nach sich ziehen. Das Facility Location Problem wurde bereits sehr intensiv in vielen unterschiedlichen Varianten untersucht. In dieser Arbeit werden drei Varianten des Problems modelliert und neue Algorithmen f{\\\"u}r sie entwickelt und bez{\\\"u}glich ihres Approximationsfaktors und ihrer Laufzeit analysiert. Jede dieser drei untersuchten Varianten hat einen besonderen Schwerpunkt. Bei der ersten Varianten handelt es sich um ein Online Problem, da hier die Eingabe nicht von Anfang an bekannt ist, sondern Schritt f{\\\"u}r Schritt enth{\\\"u}llt wird. Die Schwierigkeit hierbei besteht darin unwiderrufliche Entscheidungen treffen zu m{\\\"u}ssen ohne dabei die Zukunft zu kennen und trotzdem eine zu jeder Zeit gute L{\\\"o}sung angeben zu k{\\\"o}nnen. Der Schwerpunkt der zweiten Variante liegt auf Lokalit{\\\"a}t, die z.B. in Sensornetzwerken von großer Bedeutung ist. Hier soll eine L{\\\"o}sung verteilt und nur mit Hilfe von lokalen Information berechnet werden. Schließlich besch{\\\"a}ftigt sich die dritte Variante mit einer verteilten Berechnung, bei welcher nur eine stark beschr{\\\"a}nkte Datenmenge verschickt werden darf und dabei trotzdem ein sehr guter Approximationsfaktor erreicht werden muss. Die bei der Analyse der Approximationsfaktoren bzw. der Kompetitivit{\\\"a}t verwendeten Techniken basieren zum großen Teil auf Absch{\\\"a}tzung der primalen L{\\\"o}sung mit Hilfe einer L{\\\"o}sung des zugeh{\\\"o}rigen dualen Problems.

Allocating resources at all locations will result in the best latency but also in the highest expenses. So we need to find an optimal subset of locations which reduces the latency but also the expenses – the facility location problem (FLP). In addition, we consider resource capacity restrictions, as a resource can only serve a limited amount of users. An FLP can be globally solved. Additionally, we propose a local, distributed heuristic. This heuristic is running within the network and does not depend on a global component. No distributed, local approximations for the capacitated FLP have been proposed so far due to the complexity of the problem. We compared the heuristic with an optimal solution obtained from a mixed integer program for different network topologies.

Such backbones receive and transmit messages from/to every node in the network. Existing distributed algorithms only consider undirected graphs, which model symmetric networks with uniform transmission ranges. We are particularly interested in the well-established disk graphs, which model asymmetric networks with non-uniform transmission ranges. The corresponding graph theoretic problem seeks a strongly connected dominating-absorbent set of minimum cardinality in a digraph. A subset of nodes in a digraph is a strongly connected dominating-absorbent set if the subgraph induced by these nodes is strongly connected and each node in the graph is either in the set or has both an in-neighbor and an out-neighbor in it. We introduce the first distributed algorithm for this problem in disk graphs. The algorithm gives an O(k^4) -approximation ratio and has a runtime bound of O(Diam) where Diam is the diameter of the graph and k denotes the transmission ratio r_{max}/r_{min} with r_{max} and r_{min} being the maximum and minimum transmission range, respectively. Moreover, we apply our algorithm on the subgraph of disk graphs consisting of only bidirectional edges. Our algorithm gives an O(ln k) -approximation and a runtime bound of O(k^8 log^∗ n) , which, for bounded k , is an optimal approximation for the problem, following Lenzen and Wattenhofer’s Ω(log^∗ n) runtime lower bound for distributed constant approximation in disk graphs.","lang":"eng"}],"ddc":["040"],"user_id":"477"},{"abstract":[{"text":"Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located inside. Because the objects occlude each other, only few are visible from outside. We present a new technique, Spherical Visibility Sampling (SVS), for real-time 3D rendering of such -- possibly highly complex -- scenes. SVS exploits the occlusion and annotates hierarchically structured objects with directional visibility information in a preprocessing step. For different directions, the directional visibility encodes which objects of a scene's region are visible from the outside of the regions' enclosing bounding sphere. Since there is no need to store a separate view space subdivision as in most techniques based on preprocessed visibility, a small memory footprint is achieved. Using the directional visibility information for an interactive walkthrough, the potentially visible objects can be retrieved very efficiently without the need for further visibility tests. Our evaluation shows that using SVS allows to preprocess complex 3D scenes fast and to visualize them in real time (e.g. a Power Plant model and five animated Boeing 777 models with billions of triangles). Because SVS does not require hardware support for occlusion culling during rendering, it is even applicable for rendering large scenes on mobile devices.","lang":"eng"}],"user_id":"15415","author":[{"first_name":"Benjamin","full_name":"Eikel, Benjamin","last_name":"Eikel"},{"first_name":"Claudius","full_name":"Jähn, Claudius","last_name":"Jähn"},{"id":"146","last_name":"Fischer","full_name":"Fischer, Matthias","first_name":"Matthias"},{"last_name":"Meyer auf der Heide","id":"15523","first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm"}],"publication":"Computer Graphics Forum","volume":32,"status":"public","date_created":"2020-04-03T07:48:48Z","intvolume":" 32","_id":"16393","issue":"4","citation":{"ieee":"B.

As those measurements cover only a small part of the scene, this approach hardly allows drawing conclusions regarding the algorithm's properties at arbitrary positions in the scene. The presented method allows the systematic and position-independent evaluation of rendering algorithms. It uses an adaptive sampling approach to approximate the distribution of a property (like rendering time) for all positions in the scene.

We introduce the Multi-Algorithm-Rendering method. It automatically deploys different rendering algorithms simultaneously for a broad range of scene types. The method divides the scene into subregions and measures the behavior of different algorithms for each region in a preprocessing step. During runtime, this data is utilized to compute an estimate for the quality and running time of the available rendering algorithms from the observer's point of view. By solving an optimizing problem, the image quality can be optimized by an assignment of algorithms to regions while keeping the frame rate almost constant.\r\n"}],"place":"Berlin, Heidelberg","date_created":"2020-04-06T07:38:52Z","status":"public","publication_status":"published","publication_identifier":{"issn":["0302-9743","1611-3349"],"isbn":["9783642419133","9783642419140"]},"publication":"Advances in Visual Computing","department":[{"_id":"63"}],"author":[{"last_name":"Petring","first_name":"Ralf","full_name":"Petring, Ralf"},{"full_name":"Eikel, Benjamin","first_name":"Benjamin","last_name":"Eikel"},{"first_name":"Claudius","full_name":"Jähn, Claudius","last_name":"Jähn"},{"id":"146","last_name":"Fischer","full_name":"Fischer, Matthias","first_name":"Matthias"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"}],"doi":"10.1007/978-3-642-41914-0_44","_id":"16407","date_updated":"2022-01-06T06:52:50Z","language":[{"iso":"eng"}],"type":"book_chapter","year":"2013","citation":{"short":"R.

The difficulty is increased even more in the case of settings with multiple interacting agents. We apply the artificial homeostatic hormone system (AHHS) approach, which is inspired by the signaling network of unicellular organisms, to control a system of several independently acting agents decentrally. The approach is designed for evaluation-minimal, artificial evolution in order to be applicable to complex modular robotics scenarios. The performance of AHHS controllers is compared with neuroevolution of augmenting topologies (NEAT) in the coupled inverted pendulums benchmark. AHHS controllers are found to be better for multimodular settings. We analyze the evolved controllers with regard to the usage of sensory inputs and the emerging oscillations, and we give a nonlinear dynamics interpretation. The generalization of evolved controllers to initial conditions far from the original conditions is investigated and found to be good. Similarly, the performance of controllers scales well even with module numbers different from the original domain the controller was evolved for. Two reference implementations of a similar controller approach are reported and shown to have shortcomings. We discuss the related work and conclude by summarizing the main contributions of our work.","lang":"eng"}],"volume":18,"status":"public","date_created":"2020-10-22T09:51:39Z","author":[{"last_name":"Hamann","full_name":"Hamann, Heiko","first_name":"Heiko"},{"last_name":"Schmickl","full_name":"Schmickl, Thomas","first_name":"Thomas"},{"full_name":"Crailsheim, Karl","first_name":"Karl","last_name":"Crailsheim"}],"publication":"Artificial Life","doi":"10.1162/artl_a_00058","date_updated":"2022-01-06T06:54:21Z","language":[{"iso":"eng"}],"title":"A Hormone-Based Controller for Evaluation-Minimal Evolution in Decentrally Controlled Systems","publication_status":"published","publication_identifier":{"issn":["1064-5462","1530-9185"]},"department":[{"_id":"63"},{"_id":"238"}]},{"page":"207-218","citation":{"chicago":"Hamann, Heiko, Thomas Schmickl, Heinz Wörn, and Karl Crailsheim. “Analysis of Emergent Symmetry Breaking in Collective Decision Making.” Neural Computing and Applications 21, no. 2 (2012): 207–18. https://doi.org/10.1007/s00521-010-0368-6.","ama":"Hamann H, Schmickl T, Wörn H, Crailsheim K.

For Gaussian noise with standard deviation σ we obtain a bound of O((log3/2 n)/σ + log n).We apply our results to the analysis of the smoothed height of binary search trees and the smoothed number of comparisons in the quicksort algorithm and prove bounds of Θ(&sqrt;n/ε + log n) and Θ(n/ε+1&sqrt;n/ε + n log n), respectively, for uniform random noise from the interval [-ε,ε].

The concept of a particle we use can be seen as a simple mobile robot with the following restrictions: it can only view the state of robots it is physically connected to, is anonymous, has only a constant size memory, can only move by using other particles as an anchor point on which it pulls itself alongside, and it operates in Look-Compute-Move cycles. The main result of this work is the presentation of a random distributed local algorithm which transforms any given connected set of particles into a particular geometric shape. As an example we provide a version of this algorithm for forming a rectangle with an arbitrary predened aspect ratio.

In dieser Arbeit wird untersucht, unter welchen Voraussetzungen die Roboter sich auf einem Punkt versammeln bzw. eine Linie zwischen zwei festen Stationen bilden k{\\\"o}nnen. Daf{\\\"u}r werden mehrere Roboter-Strategien in verschiedenen Bewegungsmodellen vorgestellt. Diese Strategien werden auf ihre Effizienz hin untersucht. Es werden obere und untere Schranken f{\\\"u}r die ben{\\\"o}tigte Anzahl Runden und die Bewegungsdistanz gezeigt. In einigen F{\\\"a}llen wird außerdem die ben{\\\"o}tigte Bewegungsdistanz mit derjenigen Bewegungsdistanz verglichen, die eine optimale globale Strategie auf der gleichen Instanz ben{\\\"o}tigen w{\\\"u}rde. So werden kompetititve Faktoren hergeleitet.","lang":"eng"}],"date_created":"2017-10-17T12:42:49Z","status":"public","has_accepted_license":"1","volume":302,"file":[{"file_name":"601-Kempkes-PhD.pdf","date_created":"2018-03-15T08:16:44Z","access_level":"closed","creator":"florida","file_id":"1252","file_size":3805310,"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2018-03-15T08:16:44Z"}],"file_date_updated":"2018-03-15T08:16:44Z","publisher":"Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn","author":[{"last_name":"Kempkes","first_name":"Barbara","full_name":"Kempkes, Barbara"}],"intvolume":" 302","_id":"601","supervisor":[{"first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide","id":"15523"}],"citation":{"bibtex":"@book{Kempkes_2012, series={Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}, title={Local strategies for robot formation problems}, volume={302}, publisher={Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}, author={Kempkes, Barbara}, year={2012}, collection={Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn} }","mla":"Kempkes, Barbara.

In order to understand such kinds of dynamics, and to design distributed algorithms that behave well under dynamics, many ways to model dynamics are introduced and analyzed w.r.t. correctness and eciency of distributed algorithms. In [16], Kuhn, Lynch, and Oshman have introduced a very general, worst case type model of dynamics: The edge set of the network may change arbitrarily from step to step, the only restriction is that it is connected at all times and the set of nodes does not change. An extended model demands that a xed connected subnetwork is maintained over each time interval of length T (T-interval dynamics). They have presented, among others, algorithms for counting the number of nodes under such general models of dynamics.In this paper, we generalize their models and algorithms by adding random edge faults, i.e., we consider fault-prone dynamic networks: We assume that an edge currently existing may fail to transmit data with some probability p. We rst observe that strong counting, i.e., each node knows the correct count and stops, is not possible in a model with random edge faults. Our main two positive results are feasibility and runtime bounds for weak counting, i.e., stopping is no longer required (but still a correct count in each node), and for strong counting with an upper bound, i.e., an upper bound N on n is known to all nodes."}],"date_created":"2017-10-17T12:42:52Z","has_accepted_license":"1","status":"public","file":[{"relation":"main_file","success":1,"date_updated":"2018-03-15T06:47:15Z","content_type":"application/pdf","file_id":"1244","creator":"florida","file_size":346044,"access_level":"closed","date_created":"2018-03-15T06:47:15Z","file_name":"619-Brandes_MadHTADDS12_01.pdf"}],"publication":"Proceedings of the 4th Workshop on Theoretical Aspects of Dynamic Distributed Systems (TADDS)","file_date_updated":"2018-03-15T06:47:15Z","author":[{"first_name":"Philipp","full_name":"Brandes, Philipp","last_name":"Brandes"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"}],"_id":"619","page":"9-14","year":"2012","type":"conference","citation":{"mla":"Brandes, Philipp, and Friedhelm Meyer auf der Heide. “Distributed Computing in Fault-Prone Dynamic Networks.” Proceedings of the 4th Workshop on Theoretical Aspects of Dynamic Distributed Systems (TADDS), 2012, pp. 9–14, doi:10.1145/2414815.2414818.","bibtex":"@inproceedings{Brandes_Meyer auf der Heide_2012, series={ICPS}, title={Distributed Computing in Fault-Prone Dynamic Networks}, DOI={10.1145/2414815.2414818}, booktitle={Proceedings of the 4th Workshop on Theoretical Aspects of Dynamic Distributed Systems (TADDS)}, author={Brandes, Philipp and Meyer auf der Heide, Friedhelm}, year={2012}, pages={9–14}, collection={ICPS} }","chicago":"Brandes, Philipp, and Friedhelm Meyer auf der Heide. “Distributed Computing in Fault-Prone Dynamic Networks.” In Proceedings of the 4th Workshop on Theoretical Aspects of Dynamic Distributed Systems (TADDS), 9–14.

When opening a facility we must choose one of K different lease types to use. A lease type k has a certain lease length lk. Opening a facility i using lease type k causes a cost of f k i and ensures that i is open for the next lk time steps. In addition to costs for opening facilities, we have to take connection costs ci j into account when assigning a client j to facility i. We develop and analyze the first online algorithm for this problem that has a time-independent competitive factor.This variant of the online facility location problem was introduced by Nagarajan and Williamson [7] and is strongly related to both the online facility problem by Meyerson [5] and the parking permit problem by Meyerson [6]. Nagarajan and Williamson gave a 3-approximation algorithm for the offline problem and an O(Klogn)-competitive algorithm for the online variant. Here, n denotes the total number of clients arriving over time. We extend their result by removing the dependency on n (and thereby on the time). In general, our algorithm is O(lmax log(lmax))-competitive. Here lmax denotes the maximum lease length. Moreover, we prove that it is O(log2(lmax))-competitive for many “natural” cases. Such cases include, for example, situations where the number of clients arriving in each time step does not vary too much, or is non-increasing, or is polynomially bounded in lmax.","lang":"eng"}],"ddc":["040"],"user_id":"15504","author":[{"full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm","id":"15523","last_name":"Meyer auf der Heide"},{"last_name":"Pietrzyk","first_name":"Peter","full_name":"Pietrzyk, Peter"},{"first_name":"Peter","full_name":"Kling, Peter","last_name":"Kling"}],"publication":"Proceedings of the 19th International Colloquium on Structural Information & Communication Complexity (SIROCCO)","file_date_updated":"2018-03-14T14:14:21Z","file":[{"access_level":"closed","file_name":"636-Online_Facility_Location.pdf","date_created":"2018-03-14T14:14:21Z","relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2018-03-14T14:14:21Z","file_id":"1232","creator":"florida","file_size":173049}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:56Z","date_updated":"2022-01-06T07:03:02Z","doi":"10.1007/978-3-642-31104-8_6","series_title":"LNCS","title":"An Algorithm for Facility Leasing","department":[{"_id":"63"}],"project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt A1","_id":"5"},{"name":"SFB 901 - Project Area A","_id":"2"}]},{"_id":"638","date_updated":"2022-01-06T07:03:03Z","year":"2012","citation":{"ieee":"F.

One single, powerful visualization node is supported by a group of backend nodes with weak graphics performance. While the visualization node renders the visible objects, the backend nodes asynchronously perform visibility tests and supply the front end with visible scene objects. The visualization node stores only currently visible objects in its memory, while the scene is distributed among the backend nodes’ memory without redundancy. To efficiently compute the occlusion tests in spite of that each backend node stores only a fraction of the original geometry, we complete the scene by adding highly simplified versions of the objects stored on other nodes. We test our system with 15 backend nodes. It is able to render a ≈ 350,M polygons (≈ 8.5,GiB) large aircraft model with 20, to 30,fps and thus allows a walk-through in real-time.\r\n"}],"citation":{"short":"T. Suess, C. Koch, C. Jähn, M.

Die 3-D-Szenendaten können nach dem Dateiimport aus einem Austauschformat in eine Vielzahl unterschiedlicher Datenstrukturen überführt werden. Es muss ein geeignetes Renderingverfahren ausgewählt und eingestellt werden, welches sowohl die Eigenschaften der Szene (Zahl der Polygone, Grad der Verdeckung etc.) als auch die Fähigkeiten der Hardware berücksichtigt. Auf der einen Seite stellt die Darstellung auf mobilen Endgeräten wie Smartphones besonders hohe Anforderungen aufgrund der Speicherbeschränkung und der geringen Leistungsfähigkeit der Grafikhardware. Auf der anderen Seite stehen bei Großprojektionssystemen, wie beispielsweise dem HD-Visualisierungscenter des Heinz Nixdorf Instituts, die hohe Bildqualität bei stereoskopischer Darstellung und die Unterstützung von Trackingsystemen im Vordergrund.\r\n\r\nDer Fokus des von uns entwickelten Systems PADrend liegt in der Bereitstellung einer flexiblen und leicht erweiterbaren Grundlage für die Entwicklung und Evaluation von 3-D-Renderingalgorithmen und räumlichen Datenstrukturen im Bereich der Forschung und der universitären Ausbildung.

One option is the approach of evolutionary robotics. In this approach, the challenge is to achieve high evaluation numbers with the available resources which may even affect the feasibility of this approach. Simulations are usually applied at least in a preliminary stage of research to support controller design. However, even simulations are computationally expensive which gets even more burdensome once comprehensive studies and comparisons between different controller designs and approaches have to be done. Hence, a benchmark with low computational cost is needed that still contains the typical challenges of decentral control, is comparable, and easily manageable. We propose such a benchmark and report an empirical study of its characteristics including the transition from the single-robot setting to the multi-robot setting, typical local optima, and properties of adaptive walks through the fitness landscape."}]},{"language":[{"iso":"eng"}],"page":"62--69","citation":{"ieee":"H.

Especially for large scenes, it is necessary to remove occluded objects to achieve a frame rate that provides an interactive environment. In order to benefit from the culling properly, often hierarchical data structures are used. These data structures typically create a spatial subdivision of a given scene into axis-aligned bounding boxes. These boxes can be tested quickly, but they are not very precise. By using these boxes, the included objects are detected as visible, even if other objects occlude them (false-positives). To get perfect results, the models original geometry included in the box has to be tested, but this would require too much computational power. To overcome this problem, original objects approximations could be used, but typical methods for mesh simplification cannot be applied, because they do not create an outer hull for a given object. We present a model simplification algorithm, which generates simple outer hulls, consisting of only few more triangles than a box, while preserving an objects shape better than a corresponding bounding box. This approach is then extended to a hierarchical data structure, the so-called hull tree, that can be generated for a given scene to improve the visibility tests. Next, we present an approximative rendering algorithm, which combines the features of the hull tree with the use of inner hulls for efficient occlusion detection and global state-sorting of the visible objects.\r\n"}],"title":"Approximative occlusion culling using the hull tree","user_id":"15415","publication":"Proceedings of the Graphics Interface 2011 Conference, May 25-27, St. John's, Newfoundland, Canada","department":[{"_id":"63"}],"publisher":"Canadian Human-Computer Communications Society","author":[{"last_name":"Suess","full_name":"Suess, Tim","first_name":"Tim"},{"first_name":"Clemens","full_name":"Koch, Clemens","last_name":"Koch"},{"full_name":"Jähn, Claudius","first_name":"Claudius","last_name":"Jähn"},{"last_name":"Fischer","id":"146","first_name":"Matthias","full_name":"Fischer, Matthias"}],"editor":[{"last_name":"Brooks","first_name":"Stephen","full_name":"Brooks, Stephen"},{"full_name":"Irani, Pourang","first_name":"Pourang","last_name":"Irani"}],"date_created":"2020-07-27T19:17:03Z","status":"public","_id":"17420","date_updated":"2022-01-06T06:53:11Z","page":"79--86","citation":{"bibtex":"@inproceedings{Suess_Koch_Jähn_Fischer_2011, title={Approximative occlusion culling using the hull tree}, booktitle={Proceedings of the Graphics Interface 2011 Conference, May 25-27, St. John’s, Newfoundland, Canada}, publisher={Canadian Human-Computer Communications Society}, author={Suess, Tim and Koch, Clemens and Jähn, Claudius and Fischer, Matthias}, editor={Brooks, Stephen and Irani, Pourang}, year={2011}, pages={79--86} }","mla":"Suess, Tim, et al. “Approximative Occlusion Culling Using the Hull Tree.” Proceedings of the Graphics Interface 2011 Conference, May 25-27, St. John’s, Newfoundland, Canada, edited by Stephen Brooks and Pourang Irani, Canadian Human-Computer Communications Society, 2011, pp. 79--86.","chicago":"Suess, Tim, Clemens Koch, Claudius Jähn, and Matthias Fischer. “Approximative Occlusion Culling Using the Hull Tree.” In Proceedings of the Graphics Interface 2011 Conference, May 25-27, St. John’s, Newfoundland, Canada, edited by Stephen Brooks and Pourang Irani, 79--86.

In this thesis we consider a web computing variant with two\r\nimportant properties: First, we support the execution of coupled, massively\r\nparallel algorithms (rather than distributed data processing). And second,\r\nwe organize the system in peer-to-peer fashion.\r\n\r\nWe present the Paderborn University BSP-based Web Computing (PUB-Web) library,\r\nwhich supports the execution of parallel programs in the bulk-synchronous style\r\n(BSP) in such a web computing setting. In this thesis, we focus on important\r\ntechnical and algorithmic aspects, in particular: In order to schedule\r\nprocesses with respect to the currently available computing power, which\r\ncontinually changes in an unpredictable fashion, we need intelligent load\r\nbalancing algorithms and -- as a basic precondition -- the technical ability\r\nto migrate threads at runtime.\r\n\r\nTo achieve the latter in a way suitable for production use, compatible with\r\nrecent Java versions, available for all important platforms, and easy-to-use\r\nfor developers, we develop the PadMig thread migration and checkpointing\r\nlibrary.\r\n\r\nIn order to tackle the distributed load balancing problem, we present an\r\nalgorithm based on Distributed Heterogeneous Hash-Tables. In order to judge\r\nthe quality of the schedules produced, we perform extensive experiments to\r\ncompare several variants of the DHHT-based load balancer with the well-\r\nestablished Work Stealing algorithm, using realistic input data obtained by\r\nprofiling the utilization of several hundred PCs for a period of several\r\nmonths.\r\n\r\nBeside the available computing power, we finally also consider the network\r\nbandwidth as a secondary criterion for load balancing. For this purpose, we\r\ncluster the PUB-Web network according to bandwidth, employing a novel,\r\nfault-tolerant, adaptive, and scaling distributed clustering algorithm called\r\nDiDiC. In order to judge the quality of the clusterings produces by DiDiC,\r\nwe experimentally compare it to the well-established MCL algorithm using a\r\nsimulator."}]},{"status":"public","date_created":"2020-09-04T11:58:54Z","publication_identifier":{"isbn":["9781450307437"]},"publication_status":"published","author":[{"last_name":"Briest","full_name":"Briest, Patrick","first_name":"Patrick"},{"full_name":"Raupach, Christoph","first_name":"Christoph","last_name":"Raupach"}],"department":[{"_id":"63"}],"publication":"Proceedings of the 23rd ACM symposium on Parallelism in algorithms and architectures - SPAA '11","user_id":"15415","title":"The car sharing problem","language":[{"iso":"eng"}],"year":"2011","type":"conference","citation":{"ieee":"P.

We focus on approximation algorithms for NP-hard mechanism design problems. These algorithms need to satisfy certain monotonicity properties to ensure truthfulness. Since most of the known approximation techniques do not fulfill these properties, we study alternative techniques. Our first contribution is a quite general method to transform a pseudopolynomial algorithm into a monotone fully polynomial time approximation scheme (FPTAS). This can be applied to various problems like, e.g., knapsack, constrained shortest path, or job scheduling with deadlines. For example, the monotone FPTAS for the knapsack problem gives a very efficient, truthful mechanism for single-minded multiunit auctions. The best previous result for such auctions was a 2-appro-xi-ma-tion. In addition, we present a monotone PTAS for the generalized assignment problem with any constant number of private parameters per agent. The most efficient way to solve packing integer programs (PIPs) is linear programming–based randomized rounding, which also is in general not monotone. We show that primal-dual greedy algorithms achieve almost the same approximation ratios for PIPs as randomized rounding. The advantage is that these algorithms are inherently monotone. This way, we can significantly improve the approximation ratios of truthful mechanisms for various fundamental mechanism design problems like single-minded combinatorial auctions (CAs), unsplittable flow routing, and multicast routing. Our primal-dual approximation algorithms can also be used for the winner determination in CAs with general bidders specifying their bids through an oracle.\r\n"}],"user_id":"15415","title":"Approximation Techniques for Utilitarian Mechanism Design","language":[{"iso":"eng"}],"page":"1587-1622","type":"journal_article","citation":{"ieee":"P.

In this setting a customer sample consists of a number of nonzero values for different products and possibly an additional product ranking. Once prices are fixed, each customer chooses to buy one of the products she can afford based on some predefined selection rule. We distinguish between the min-buying, max-buying, and rank-buying models. Some of our results also extend to single-minded pricing, in which case products are strict complements and every customer seeks to buy a single set of products, which she purchases if the sum of prices is below her valuation for that set. For the min-buying model we show that the revenue maximization problem is not approximable within factor $\\mathcal{O}(\\log^{\\varepsilon}|\\mathcal{C}|)$ for some constant $\\varepsilon>0$, unless $\\mathrm{NP}\\subseteq\\mathrm{DTIME}(n^{\\mathcal{O}(\\log\\log n)})$, thereby almost closing the gap between the known algorithmic results and previous lower bounds. We also prove inapproximability within $\\mathcal{O}(\\ell^{\\varepsilon})$, $\\ell$ being an upper bound on the number of nonzero values per customer, and $\\mathcal{O}(|\\mathcal{P}|^{\\varepsilon})$ under slightly stronger assumptions and provide matching upper bounds. Surprisingly, these hardness results hold even if a price ladder constraint, i.e., a predefined order on the prices of all products, is given. Without the price ladder constraint we obtain similar hardness results for the special case of uniform valuations, i.e., the case that every customer has identical values for all the products she is interested in, assuming specific hardness of the balanced bipartite independent set problem in constant degree graphs or hardness of refuting random 3CNF formulas. Introducing a slightly more general problem definition in which customers are given as an explicit probability distribution, we obtain inapproximability within $\\mathcal{O}(|\\mathcal{P}|^{\\varepsilon})$ assuming $\\mathrm{NP}\\nsubseteq\\bigcap_{\\delta>0}\\mathrm{BPTIME}(2^{\\mathcal{O}(n^{\\delta})})$. These results apply to single-minded pricing as well. For the max-buying model a polynomial-time approximation scheme exists if a price ladder is given. We give a matching lower bound by proving strong NP-hardness. Assuming limited product supply, we analyze a generic local search algorithm and prove that it is 2-approximate. Finally, we discuss implications for the rank-buying model.\r\n"}],"publication_identifier":{"issn":["0097-5397","1095-7111"]},"publication_status":"published","status":"public","date_created":"2021-09-03T10:48:52Z","author":[{"first_name":"Patrick","full_name":"Briest, Patrick","last_name":"Briest"},{"first_name":"Piotr","full_name":"Krysta, Piotr","last_name":"Krysta"}],"department":[{"_id":"63"}],"publication":"SIAM Journal on Computing"},{"status":"public","date_created":"2020-12-12T11:15:30Z","publication_status":"published","publication_identifier":{"isbn":["9783642183805","9783642183812"],"issn":["0302-9743","1611-3349"]},"author":[{"last_name":"Cord-Landwehr","first_name":"Andreas","full_name":"Cord-Landwehr, Andreas"},{"last_name":"Degener","full_name":"Degener, Bastian","first_name":"Bastian"},{"last_name":"Fischer","full_name":"Fischer, Matthias","first_name":"Matthias"},{"last_name":"Hüllmann","full_name":"Hüllmann, Martina","first_name":"Martina"},{"full_name":"Kempkes, Barbara","first_name":"Barbara","last_name":"Kempkes"},{"first_name":"Alexander","full_name":"Klaas, Alexander","last_name":"Klaas"},{"last_name":"Kling","first_name":"Peter","full_name":"Kling, Peter"},{"last_name":"Kurras","full_name":"Kurras, Sven","first_name":"Sven"},{"full_name":"Märtens, Marcus","first_name":"Marcus","last_name":"Märtens"},{"last_name":"auf der Heide","full_name":"auf der Heide, Friedhelm Meyer","first_name":"Friedhelm Meyer"},{"last_name":"Raupach","full_name":"Raupach, Christoph","first_name":"Christoph"},{"last_name":"Swierkot","full_name":"Swierkot, Kamil","first_name":"Kamil"},{"last_name":"Warner","id":"3902","first_name":"Daniel","full_name":"Warner, Daniel"},{"last_name":"Weddemann","full_name":"Weddemann, Christoph","first_name":"Christoph"},{"last_name":"Wonisch","first_name":"Daniel","full_name":"Wonisch, Daniel"}],"publication":"SOFSEM 2011: Theory and Practice of Computer Science","department":[{"_id":"63"}],"user_id":"3902","title":"Collisionless Gathering of Robots with an Extent","place":"Berlin, Heidelberg","language":[{"iso":"eng"}],"type":"book_chapter","year":"2011","citation":{"apa":"Cord-Landwehr, A., Degener, B., Fischer, M., Hüllmann, M., Kempkes, B., Klaas, A., … Wonisch, D.

One single visualization node, equipped with a high-end graphics adapter, is supported by a group of backend nodes with weak graphics performance. The objects of the scene are distributed among these backend nodes, they serve two purposes: First, they provide an out-of-core memory system for the visualization node. Second, they assist the visualization node's rendering by performing visibility calculations and only sending visible objects to the visualization node. In order to obtain fast rendering with our system, we have to distribute the objects among the backend nodes in a way that does not only guarantee an even distribution of the objects, but also an even distribution of the visibility calculations and the amount of data send to the visualization node. We identify necessary properties of the distribution and argue that a random distribution is a good candidate. Further, in order to reduce the number of objects sent to the visualization node per frame, we employ an approximate hierarchical occlusion culling in each backend node. For this, they are equipped, in addition to the objects assigned to them, with simplified versions of the other objects of the 3D scene. The visualization node is equipped with 512 MiB video memory and supported by 15 backend nodes. This system is able to render a approx. 350 million polygons (approx. 8.5 GiB) large aircraft model between 20 - 30 fps and thus allows a walkthrough in real-time.","lang":"eng"}],"date_created":"2020-08-24T14:14:10Z","status":"public","has_accepted_license":"1","department":[{"_id":"63"}],"file_date_updated":"2020-08-24T14:13:46Z","author":[{"first_name":"Tim","full_name":"Suess, Tim","last_name":"Suess"},{"last_name":"Koch","first_name":"Clemens","full_name":"Koch, Clemens"},{"full_name":"Jähn, Claudius","first_name":"Claudius","last_name":"Jähn"},{"full_name":"Fischer, Matthias","first_name":"Matthias","id":"146","last_name":"Fischer"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"}],"file":[{"file_size":3091853,"file_id":"18195","creator":"koala","content_type":"application/pdf","date_updated":"2020-08-24T14:13:46Z","relation":"main_file","success":1,"file_name":"pre-03-2011-5220.pdf","date_created":"2020-08-24T14:13:46Z","access_level":"closed"}],"date_updated":"2022-01-06T06:53:27Z","_id":"18194","citation":{"ieee":"T.
