Given an arbitrarily distributed (yet connected)\r\nswarm of robots, the gathering problem on the grid is to locate all robots\r\nwithin a $2\\times 2$-sized area that is not known beforehand. Two robots are\r\nconnected if they are vertical or horizontal neighbors on the grid. The\r\nlocality constraint means that no global control, no compass, no global\r\ncommunication and only local vision is available; hence, a robot can only see\r\nits grid neighbors up to a constant $L_1$-distance, which also limits its\r\nmovements. A robot can move to one of its eight neighboring grid cells and if\r\ntwo or more robots move to the same location they are \\emph{merged} to be only\r\none robot. The locality constraint is the significant challenging issue here,\r\nsince robot movements must not harm the (only globally checkable) swarm\r\nconnectivity. For solving the gathering problem, we provide a synchronous\r\nalgorithm -- executed by every robot -- which ensures that robots merge without\r\nbreaking the swarm connectivity. In our model, robots can obtain a special\r\nstate, which marks such a robot to be performing specific connectivity\r\npreserving movements in order to allow later merge operations of the swarm.\r\nCompared to the grid, for gathering in the Euclidean plane for the same robot\r\nand time model the best known upper bound is $\\mathcal{O}(n^2)$.","lang":"eng"}],"user_id":"15415","title":"Asymptotically Optimal Gathering on a Grid","language":[{"iso":"eng"}],"year":"2016","citation":{"ieee":"A.

In particular, we focus on model transformation by example. The definition and implementation of model transformations is a task frequently carried out by domain experts, hence, a (semi-)automatic approach is desirable. This application is challenging because the underlying search space has rich semantics, is high-dimensional, and unstructured. Hence, a computationally brute-force approach would be unscalable and potentially infeasible. To address that problem, we develop a sophisticated approach of designing complex mutation operators. We define ‘patterns’ for constructing mutation operators and report a successful case study. Furthermore, the code of the evolved model transformation is required to have high maintainability and extensibility, that is, the code should be easily readable by domain experts. We report an evaluation of this approach in a software engineering case study.","lang":"eng"}],"user_id":"57458","ddc":["040"]},{"title":"Über die Rolle von Informationen in Verkehrsnetzwerken","user_id":"14052","date_created":"2017-12-19T10:10:17Z","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subproject A3","_id":"7"},{"_id":"2","name":"SFB 901 - Project Area A"}],"status":"public","department":[{"_id":"63"},{"_id":"541"}],"author":[{"full_name":"Handirk, Tobias","first_name":"Tobias","last_name":"Handirk"}],"publisher":"Universität Paderborn","_id":"1082","date_updated":"2022-01-06T06:50:51Z","year":"2016","type":"bachelorsthesis","citation":{"short":"T.

These allocationsare used in a game-theoretic context for routing choices, whichwe formalize in progressive filling games (PFGs). We present avariety of results for equilibria in PFGs. We show that these gamespossess pure Nash and strong equilibria. While computation ingeneral is NP-hard, there are polynomial-time algorithms forprominent classes of Max-Min-Fair Games (MMFG), includingthe case when all users have the same source-destination pair.We characterize prices of anarchy and stability for pure Nashand strong equilibria in PFGs and MMFGs when players havedifferent or the same source-destination pairs.

Given is a graph in which each node serves two roles: it is a strategic client stating requests as well as a potential location for a facility. In each time step one client states a request which induces private costs equal to the distance to the closest facility. Before serving, the clients may collectively decide to open new facilities, sharing the corresponding price. Instead of optimizing the global costs, each client acts selfishly. The prices of new facilities vary between nodes and also change over time, but are always bounded by some fixed value α. Both the requests as well as the facility prices are given by an online sequence and are not known in advance.We characterize the optimal strategies of the clients and analyze their overall performance in comparison to a centralized offline solution. If all players optimize their own competitiveness, the global performance of the system is O(√α⋅α) times worse than the offline optimum. A restriction to a natural subclass of strategies improves this result to O(α). We also show that for fixed facility costs, we can find strategies such that this bound further improves to O(√α).","lang":"eng"}],"language":[{"iso":"eng"}],"series_title":"LNCS","doi":"10.1007/978-3-319-48749-6_43","date_updated":"2022-01-06T06:52:10Z","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt A1","_id":"5"},{"_id":"7","name":"SFB 901 - Subproject A3"},{"_id":"2","name":"SFB 901 - Project Area A"}],"department":[{"_id":"63"},{"_id":"541"}],"title":"Strategic Online Facility Location"},{"title":"Proceedings of the 17th ACM International Symposium on Mobile Ad Hoc Networking and Computing (MobiHoc)","user_id":"15504","department":[{"_id":"63"}],"publisher":"ACM","editor":[{"first_name":"Falko","full_name":"Dressler, Falko","last_name":"Dressler"},{"last_name":"Meyer auf der Heide","id":"15523","first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm"}],"date_created":"2017-10-17T12:41:23Z","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt C4","_id":"16"},{"name":"SFB 901 - Project Area C","_id":"4"}],"status":"public","conference":{"location":"Paderborn, Germany","start_date":"2016-07-04","name":"MobiHoc","end_date":"2016-07-08"},"_id":"163","date_updated":"2022-01-06T06:52:48Z","doi":"10.1145/2942358","year":"2016","type":"conference_editor","citation":{"mla":"Dressler, Falko, and Friedhelm Meyer auf der Heide, editors.

Given an arbitrarily distributed (yet connected) swarm of robots, the gathering problem on the grid is to locate all robots within a 2x2- sized area that is not known beforehand. Two robots are connected if they are vertical or horizontal neighbors on the grid. The locality constraint means that no global control, no compass, no global communication and only local vision is available; hence, a robot can only see its grid neighbors up to a constant L1-distance, which also limits its movements. A robot can move to one of its eight neighboring grid cells and if two or more robots move to the same location they are merged to be only one robot. The locality constraint is the significant challenging issue here, since robot move- ments must not harm the (only globally checkable) swarm connectivity. For solving the gathering problem, we provide a synchronous algorithm { executed by every robot { which ensures that robots merge without breaking the swarm con- nectivity. In our model, robots can obtain a special state, which marks such a robot to be performing specific connec- tivity preserving movements in order to allow later merge operations of the swarm.

Initially, the robots form a closed chain on the grid and must keep this connectivity during the whole process of their gathering. Connectivity means, that neighboring robots of the chain need to be positioned at the same or neighboring points of the grid. In our model, gathering means to keep shortening the chain until the robots are located inside a 2*2 subgrid. Our model is completely local (no global control, no global coordinates, no compass, no global communication or vision, ...). Each robot can only see its next constant number of left and right neighbors on the chain. This fixed constant is called the viewing path length. All its operations and detections are restricted to this constant number of robots. Other robots, even if located at neighboring or the same grid point cannot be detected. Only based on the relative positions of its detectable chain neighbors, a robot can decide to obtain a certain state. Based on this state and their local knowledge, the robots do local modifications to the chain by moving to neighboring grid points without breaking the chain. These modifications are performed without the knowledge whether they lead to a global progress or not. We assume the fully synchronous FSYNC model. For this problem, we present a gathering algorithm which needs linear time. This result generalizes a result, where an open chain with specified distinguishable (and fixed) endpoints is considered.

Classically, decisions for such problems are considered as final: one buys the goods. However, in many real world applications, there is a shift away from the idea of buying goods. Instead, leasing is often a more flexible and lucrative business model. Research has realized this shift and recently initiated the theoretical study of leasing models (Anthony and Gupta in Proceedings of the integer programming and combinatorial optimization: 12th International IPCO Conference, Ithaca, NY, USA, June 25–27, 2007; Meyerson in Proceedings of the 46th Annual IEEE Symposium on Foundations of Computer Science (FOCS 2005), 23–25 Oct 2005, Pittsburgh, PA, USA, 2005; Nagarajan and Williamson in Discret Optim 10(4):361–370, 2013) We extend this line of work and suggest a more systematic study of leasing aspects for a class of online optimization problems. We provide two major technical results. We introduce the leasing variant of online set multicover and give an O(log(mK)logn)-competitive algorithm (with n, m, and K being the number of elements, sets, and leases, respectively). Our results also imply improvements for the non-leasing variant of online set cover. Moreover, we extend results for the leasing variant of online facility location. Nagarajan and Williamson (Discret Optim 10(4):361–370, 2013) gave an O(Klogn)-competitive algorithm for this problem (with n and K being the number of clients and leases, respectively). We remove the dependency on n (and, thereby, on time). In general, this leads to a bound of O(lmaxloglmax) (with the maximal lease length lmax). For many natural problem instances, the bound improves to O(K2)."}]},{"title":"The Monotone Circuit Value Problem with Bounded Genus Is in NC","project":[{"name":"SFB 901","_id":"1"},{"_id":"5","name":"SFB 901 - Subprojekt A1"},{"_id":"2","name":"SFB 901 - Project Area A"}],"department":[{"_id":"63"}],"doi":"10.1007/978-3-319-42634-1_8","date_updated":"2022-01-06T06:51:57Z","language":[{"iso":"eng"}],"series_title":"LNCS","user_id":"477","ddc":["000"],"abstract":[{"lang":"eng","text":"We present an efficient parallel algorithm for the general Monotone Circuit Value Problem (MCVP) with n gates and an underlying graph of bounded genus k.

In addition to extending this result from genus 1 to any bounded genus k, and unlike the work reported by Limaye et al., we do not require a precomputed embedding to be given. Most importantly, our results imply that given a P-complete problem, it is possible to find an algorithm that makes the problem fall into NC by fixing one or more parameters. Hence, we deduce the interesting analogy: Fixed Parameter Parallelizable (FPP) is with respect to P-complete what Fixed Parameter Tractable (FPT) is with respect to NP-complete.

PeerfactSim.KOM comes with an extensive layer model to support various facets and protocols of peer-to-peer networking. In this article, we describe PeerfactSim.KOM and show how it can be used for detailed measurements of large-scale peer-to-peer networks. We enhanced PeerfactSim.KOM with a fine-grained analyzer concept, with exhaustive automated measurements and gnuplot generators as well as a coordination control to evaluate sets of experiment setups in parallel. Thus, by configuring all experiments and protocols only once and starting the simulator, all desired measurements are performed, analyzed, evaluated, and combined, resulting in a holistic environment for the comparative evaluation of peer-to-peer systems. An immediate comparison of different configurations and overlays under different aspects is possible directly after the execution without any manual post-processing.

These robot-plant bio-hybrids create synergies that allow for new functions of plants and robots.

The bio-hybrid is an example of mixed societies between 'hard' artificial and 'wet' natural life, which enables an interaction between natural and artificial ecologies. They form an embodied, self-organizing, and distributed cognitive system which is supposed to grow and develop over long periods of time resulting in the creation of meaningful architectural structures. A key idea is to assign equal roles to robots and plants in order to create a highly integrated, symbiotic system. Besides the gain of knowledge, this project has the objective to create a bio-hybrid system with a defined function and application -- growing architectural artifacts."}],"title":"Flora Robotica - Mixed Societies of Symbiotic Robot-Plant Bio-Hybrids","user_id":"15415"},{"abstract":[{"lang":"eng","text":"Recent approaches in evolutionary robotics (ER) propose to generate behavioral diversity in order to evolve desired behaviors more easily. These approaches require the definition of a behavioral distance, which often includes task-specific features and hence a priori knowledge. Alternative methods, which do not explicitly force selective pressure towards diversity (SPTD) but still generate it, are known from the field of artificial life, such as in artificial ecologies (AEs). In this study, we investigate how SPTD is generated without task-specific behavioral features or other forms of a priori knowledge and detect how methods of generating SPTD can be transferred from the domain of AE to ER. A promising finding is that in both types of systems, in systems from ER that generate behavioral diversity and also in the investigated speciation model, selective pressure is generated towards unpopulated regions of search space. In a simple case study we investigate the practical implications of these findings and point to options for transferring the idea of self-organizing SPTD in AEs to the domain of ER."}],"user_id":"15415","title":"Lessons from Speciation Dynamics: How to Generate Selective Pressure Towards Diversity","author":[{"first_name":"Heiko","full_name":"Hamann, Heiko","last_name":"Hamann"}],"publication":"Artificial Life","department":[{"_id":"63"},{"_id":"238"}],"status":"public","date_created":"2020-10-08T14:36:25Z","publication_status":"published","publication_identifier":{"issn":["1064-5462","1530-9185"]},"_id":"19962","date_updated":"2022-01-06T06:54:17Z","doi":"10.1162/artl_a_00186","language":[{"iso":"eng"}],"year":"2015","type":"journal_article","citation":{"ama":"Hamann H.

Potentially, the complexity of evolving a successful controller for a given task can be reduced by integrating a priori knowledge into the fitness function which complicates the comparability of studies in evolutionary robotics. Still, there are only few publications that study the actual effects of different fitness functions on the robot's performance. In this paper, we follow the fitness function classification of Nelson et al. (2009) and investigate a selection of four classes of fitness functions that require different degrees of a priori knowledge. The robot controllers are evolved in simulation using NEAT and we investigate different tasks including obstacle avoidance and (periodic) goal homing. The best evolved controllers were then post-evaluated by examining their potential for adaptation, determining their convergence rates, and using cross-comparisons based on the different fitness function classes. The results confirm that the integration of more a priori knowledge can simplify a task and show that more attention should be paid to fitness function classes when comparing different studies.","lang":"eng"}]},{"author":[{"last_name":"Hamann","first_name":"Heiko","full_name":"Hamann, Heiko"},{"last_name":"Schmickl","full_name":"Schmickl, Thomas","first_name":"Thomas"},{"last_name":"Zahadat","full_name":"Zahadat, Payam","first_name":"Payam"}],"publisher":"MIT Press","department":[{"_id":"63"},{"_id":"238"}],"publication":"13th European Conference on Artificial Life (ECAL 2015)","status":"public","date_created":"2020-10-13T08:50:38Z","title":"Evolving Collective Behaviors With Diverse But Predictable Sensor States","user_id":"15415","year":"2015","citation":{"short":"H.

In weighted congestion games with linear latency functions, the existence of pure Nash equilibria is guaranteed by a potential function argument. Unfortunately, this proof of existence is inefficient and computing pure Nash equilibria in such games is a PLS-hard problem even when all players have unit weights. The situation gets worse when superlinear (e.g., quadratic) latency functions come into play; in this case, the Nash dynamics of the game may contain cycles and pure Nash equilibria may not even exist. Given these obstacles, we consider approximate pure Nash equilibria as alternative solution concepts. A ρ--approximate pure Nash equilibrium is a state of a (weighted congestion) game from which no player has any incentive to deviate in order to improve her cost by a multiplicative factor higher than ρ. Do such equilibria exist for small values of ρ? And if so, can we compute them efficiently?We provide positive answers to both questions for weighted congestion games with polynomial latency functions by exploiting an “approximation” of such games by a new class of potential games that we call Ψ-games. This allows us to show that these games have d!-approximate pure Nash equilibria, where d is the maximum degree of the latency functions. Our main technical contribution is an efficient algorithm for computing O(1)-approximate pure Nash equilibria when d is a constant. For games with linear latency functions, the approximation guarantee is 3+√5/2 + Oγ for arbitrarily small γ > 0; for latency functions with maximum degree d≥ 2, it is d2d+o(d). The running time is polynomial in the number of bits in the representation of the game and 1/γ. As a byproduct of our techniques, we also show the following interesting structural statement for weighted congestion games with polynomial latency functions of maximum degree d ≥ 2: polynomially-long sequences of best-response moves from any initial state to a dO(d2)-approximate pure Nash equilibrium exist and can be efficiently identified in such games as long as d is a constant.To the best of our knowledge, these are the first positive algorithmic results for approximate pure Nash equilibria in weighted congestion games. Our techniques significantly extend our recent work on unweighted congestion games through the use of Ψ-games. The concept of approximating nonpotential games by potential ones is interesting in itself and might have further applications."}],"user_id":"477","ddc":["040"],"type":"journal_article","year":"2015","citation":{"ieee":"I.

The player's utility is at most the sum of these demands, provided they are fully satisfied. Every resource has a limited capacity and if it is exceeded by the total demand, it has to be split between the players. Since these games generally do not have pure Nash equilibria, we consider approximate pure Nash equilibria, in which no player can improve her utility by more than some fixed factor $\\alpha$ through unilateral strategy changes. There is a threshold $\\alpha_\\delta$ (where $\\delta$ is a parameter that limits the demand of each player on a specific resource) such that $\\alpha$-approximate pure Nash equilibria always exist for $\\alpha \\geq \\alpha_\\delta$, but not for $\\alpha < \\alpha_\\delta$. We give both upper and lower bounds on this threshold $\\alpha_\\delta$ and show that the corresponding decision problem is ${\\sf NP}$-hard. We also show that the $\\alpha$-approximate price of anarchy for BAGs is $\\alpha+1$. For a restricted version of the game, where demands of players only differ slightly from each other (e.g. symmetric games), we show that approximate Nash equilibria can be reached (and thus also be computed) in polynomial time using the best-response dynamic. Finally, we show that a broader class of utility-maximization games (which includes BAGs) converges quickly towards states whose social welfare is close to the optimum.","lang":"eng"}],"ddc":["040"],"user_id":"14052","publication":"Proceedings of the 8th International Symposium on Algorithmic Game Theory (SAGT)","file_date_updated":"2018-03-21T09:29:34Z","author":[{"last_name":"Drees","full_name":"Drees, Maximilian","first_name":"Maximilian"},{"last_name":"Feldotto","id":"14052","first_name":"Matthias","orcid":"0000-0003-1348-6516","full_name":"Feldotto, Matthias"},{"last_name":"Riechers","first_name":"Sören","full_name":"Riechers, Sören"},{"first_name":"Alexander","full_name":"Skopalik, Alexander","last_name":"Skopalik","id":"40384"}],"file":[{"access_level":"closed","file_name":"271-chp_3A10.1007_2F978-3-662-48433-3_14.pdf","date_created":"2018-03-21T09:29:34Z","date_updated":"2018-03-21T09:29:34Z","content_type":"application/pdf","relation":"main_file","success":1,"file_size":256718,"file_id":"1475","creator":"florida"}],"date_created":"2017-10-17T12:41:45Z","has_accepted_license":"1","status":"public","date_updated":"2022-01-06T06:57:34Z","doi":"10.1007/978-3-662-48433-3_14","series_title":"Lecture Notes in Computer Science","external_id":{"arxiv":["1507.02908"]},"title":"On Existence and Properties of Approximate Pure Nash Equilibria in Bandwidth Allocation Games","department":[{"_id":"63"},{"_id":"541"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A3","_id":"7"},{"_id":"16","name":"SFB 901 - Subproject C4"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"4","name":"SFB 901 - Project Area C"}]},{"author":[{"first_name":"Alexander","full_name":"Mäcker, Alexander","last_name":"Mäcker","id":"13536"},{"last_name":"Malatyali","full_name":"Malatyali, Manuel","first_name":"Manuel"},{"first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide","id":"15523"},{"last_name":"Riechers","full_name":"Riechers, Sören","first_name":"Sören"}],"file_date_updated":"2018-03-21T09:28:34Z","publication":"Algorithms and Data Structures: 14th International Symposium, WADS 2015, Victoria, BC, Canada, August 5-7, 2015.

Each agent aims for a central position at minimum cost for creating edges. In particular, the general model (Fabrikant et al., PODC'03) became popular for studying the structure of the Internet or social networks. Despite its significance, locality in this game was first studied only recently (Bilò et al., SPAA'14), where a worst case locality model was presented, which came with a high efficiency loss in terms of quality of equilibria. Our main contribution is a new and more optimistic view on locality: agents are limited in their knowledge and actions to their local view ranges, but can probe different strategies and finally choose the best. We study the influence of our locality notion on the hardness of computing best responses, convergence to equilibria, and quality of equilibria. Moreover, we compare the strength of local versus non-local strategy changes. Our results address the gap between the original model and the worst case locality variant. On the bright side, our efficiency results are in line with observations from the original model, yet we have a non-constant lower bound on the Price of Anarchy."}],"ddc":["040"],"user_id":"477","file_date_updated":"2018-03-21T09:27:12Z","publication":"Proceedings of the 40th Conference on Mathematical Foundations of Computer Science (MFCS)","author":[{"last_name":"Cord-Landwehr","first_name":"Andreas","full_name":"Cord-Landwehr, Andreas"},{"last_name":"Lenzner","full_name":"Lenzner, Pascal","first_name":"Pascal"}],"file":[{"content_type":"application/pdf","date_updated":"2018-03-21T09:27:12Z","success":1,"relation":"main_file","file_size":279995,"file_id":"1472","creator":"florida","access_level":"closed","date_created":"2018-03-21T09:27:12Z","file_name":"275-978-3-662-48054-0_21.pdf"}],"date_created":"2017-10-17T12:41:45Z","has_accepted_license":"1","status":"public"},{"_id":"277","date_updated":"2022-01-06T06:57:44Z","citation":{"ieee":"N.

We propose to schedule these flows by a centralized controller, which determines when to transmit each flow and which path to use. Two scheduling models are presented in this paper.

In this problem the input consists of a set of users and a set of base stations. Each user has a list of requests, each consisting of a base station, a frequency demand, and a profit that may be gained by scheduling this request. The goal is to find a maximum profit set of user requests S that satisfies the following conditions: (i) S contains at most one request per user, (ii) the frequency sets allotted to requests in S that correspond to the same base station are pairwise non-intersecting, and (iii) the QoS received by any user at any frequency is reasonable according to an interference model. In this paper we consider two variants of bandwidth allocation with multiple interferences. In the first each request specifies a demand that can be satisfied by any subset of frequencies that is large enough. In the second each request specifies a specific frequency interval. Furthermore, we consider two interference models, multiplicative and additive. We show that these problems are extremely hard to approximate if the interferences depend on both the interfered and the interfering base stations. On the other hand, we provide constant factor approximation algorithms for both variants of bandwidth allocation with multiple interferences for the case where the interferences depend only on the interfering base stations. We also consider a restrictive special case that is closely related to the Knapsack problem. We show that this special case is NP-hard and that it admits an FPTAS.

In swarm systems most of the observed complexity is based on motion of simple entities. Similarly, statistical mechanics focuses on collective properties induced by the motion of many interacting particles. In this article we apply methods from statistical mechanics to swarm systems. We try to explain the emergent behavior of a simulated swarm by applying methods based on the fluctuation theorem. Empirical results indicate that swarms are able to produce negative entropy within an isolated subsystem due to frozen accidents. Individuals of a swarm are able to locally detect fluctuations of the global entropy measure and store them, if they are negative entropy productions. By accumulating these stored fluctuations over time the swarm as a whole is producing negative entropy and the system ends up in an ordered state. We claim that this indicates the existence of an inverted fluctuation theorem for emergent self-organizing dissipative systems. This approach bears the potential of general applicability."}],"page":"77-93","citation":{"short":"H. Hamann, T. Schmickl, K. Crailsheim, Artificial Life 20 (2014) 77–93.","ieee":"H. Hamann, T.

Globally defined qualities such as consensus time and decision accuracy are both difficult to predict and difficult to guarantee. We present the weighted voter model which implements a self-organized collective decision making process. We provide an ODE model, a master equation model (numerically solved by the Gillespie algorithm), and agent-based simulations of the proposed decision-making strategy. This set of models enables us to investigate the system behavior in the thermodynamic limit and to investigate finite-size effects due to random fluctuations. Based on our results, we give minimum requirements to guarantee consensus on the optimal decision, a minimum swarm size to guarantee a certain accuracy, and we show that the proposed approach scales with system size and is robust to noise."}],"year":"2014","type":"conference","citation":{"ieee":"M.

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.","lang":"eng"}],"user_id":"15415","ddc":["040"],"file":[{"file_id":"1403","creator":"florida","file_size":485767,"success":1,"relation":"main_file","date_updated":"2018-03-20T07:17:38Z","content_type":"application/pdf","date_created":"2018-03-20T07:17:38Z","file_name":"368-BKMNRS14.pdf","access_level":"closed"}],"author":[{"full_name":"Brinkmann, Andre","first_name":"Andre","last_name":"Brinkmann"},{"last_name":"Kling","full_name":"Kling, Peter","first_name":"Peter"},{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"},{"first_name":"Lars","full_name":"Nagel, Lars","last_name":"Nagel"},{"last_name":"Riechers","first_name":"Sören","full_name":"Riechers, Sören"},{"full_name":"Suess, Tim ","first_name":"Tim ","last_name":"Suess"}],"publication":"Proceedings of the 26th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)","file_date_updated":"2018-03-20T07:17:38Z","status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:03Z","_id":"368","type":"conference","year":"2014","citation":{"chicago":"Brinkmann, Andre, Peter Kling, Friedhelm Meyer auf der Heide, Lars Nagel, Sören Riechers, and Tim Suess. “Scheduling Shared Continuous Resources on Many-Cores.” In Proceedings of the 26th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA), 128–37, 2014. https://doi.org/10.1145/2612669.2612698.","apa":"Brinkmann, A., Kling, P., Meyer auf der Heide, F., Nagel, L., Riechers, S., & Suess, T.

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.","lang":"eng"}]},{"abstract":[{"text":"In this paper we study the potential function in congestion games.

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.

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"}],"ddc":["040"],"user_id":"14052","date_updated":"2022-01-06T07:00:20Z","doi":"10.1109/P2P.2014.6934300","department":[{"_id":"79"},{"_id":"63"},{"_id":"541"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area A","_id":"2"},{"_id":"5","name":"SFB 901 - Subproject A1"}],"external_id":{"arxiv":["1408.0395"]},"title":"HSkip+: A Self-Stabilizing Overlay Network for Nodes with Heterogeneous Bandwidths"},{"supervisor":[{"id":"15523","last_name":"Meyer auf der Heide","full_name":"Meyer auf der Heide, Friedhelm","first_name":"Friedhelm"}],"citation":{"ieee":"P.

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.

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","title":"Darstellung heterogener 3-D-Szenen in Echtzeit","user_id":"15415"},{"place":"Universität Paderborn","title":"Spherical visibility sampling : preprocessed visibility for occlusion culling in complex 3D scenes","user_id":"15415","related_material":{"link":[{"relation":"confirmation","url":"http://nbn-resolving.de/urn:nbn:de:hbz:466:2-12683"}]},"department":[{"_id":"63"}],"author":[{"full_name":"Eikel, Benjamin","first_name":"Benjamin","last_name":"Eikel"}],"date_created":"2020-07-29T09:11:23Z","status":"public","_id":"17440","date_updated":"2022-01-06T06:53:12Z","citation":{"short":"B.

We present and discuss this problem in the context of large-scale powerful (radar/camera) sensor networks, but we believe it has important applications on the admission of large flows in other networks as well. 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."}],"extern":"1","user_id":"83983","author":[{"last_name":"Cohen","first_name":"R.","full_name":"Cohen, R."},{"last_name":"Nudelman","first_name":"I.","full_name":"Nudelman, I."},{"last_name":"Polevoy","id":"83983","first_name":"Gleb","full_name":"Polevoy, Gleb"}],"publication":"Networking, IEEE/ACM Transactions on","keyword":["Approximation algorithms","Approximation methods","Bandwidth","Logic gates","Radar","Vectors","Wireless sensor networks","Dependent flow scheduling","sensor networks"],"status":"public","date_created":"2020-08-06T15:22:05Z","volume":21,"intvolume":" 21","_id":"17663","issue":"5","type":"journal_article","citation":{"chicago":"Cohen, R., I.

In contrast to general dynamic networks, our dynamic networks are unit disk graphs, i.e., nodes are embedded into the Euclidean plane and two nodes are connected if and only if their distance is at most R. 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."}],"status":"public","has_accepted_license":"1","date_created":"2017-10-17T12:42:25Z","author":[{"full_name":"Abshoff, Sebastian","first_name":"Sebastian","last_name":"Abshoff"},{"full_name":"Benter, Markus","first_name":"Markus","last_name":"Benter"},{"last_name":"Cord-Landwehr","full_name":"Cord-Landwehr, Andreas","first_name":"Andreas"},{"last_name":"Malatyali","full_name":"Malatyali, Manuel","first_name":"Manuel"},{"last_name":"Meyer auf der Heide","id":"15523","first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm"}],"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","file":[{"file_name":"477-geometric-dynamic-networks_01.pdf","date_created":"2018-03-15T14:06:38Z","access_level":"closed","creator":"florida","file_id":"1325","file_size":193169,"relation":"main_file","success":1,"date_updated":"2018-03-15T14:06:38Z","content_type":"application/pdf"}],"_id":"477","citation":{"ieee":"S.
