text: AbstractConsider a set of jobs connected
to a directed acyclic task graph with a fixed source and sink. The edges of this
graph model precedence constraints and the jobs have to be scheduled with respect
to those. We introduce the server cloud scheduling problem, in which the jobs
have to be processed either on a single local machine or on one of infinitely
many cloud machines. For each job, processing times both on the server and in
the cloud are given. Furthermore, for each edge in the task graph, a communication
delay is included in the input and has to be taken into account if one of the
two jobs is scheduled on the server and the other in the cloud. The server processes
jobs sequentially, whereas the cloud can serve as many as needed in parallel,
but induces costs. We consider both makespan and cost minimization. The main results
are an FPTAS for the makespan objective for graphs with a constant source and
sink dividing cut and strong hardness for the case with unit processing times
and delays.

text: "The famous $k$-Server Problem covers plenty of resource allocation scenarios,
and several variations have been studied extensively for decades. However, to
the best of our knowledge, no research has considered the problem if the servers
are not identical and requests can express which specific servers should serve
them. Therefore, we present a new model generalizing the $k$-Server Problem by
*preferences* of the requests and proceed to study it in a uniform metric space
for deterministic online algorithms (the special case of paging).\r\n\r\nIn our
model, requests can either demand to be answered by any server (*general requests*)
or by a specific one (*specific requests*). If only general requests appear, the
instance is one of the original $k$-Server Problem, and a lower bound for the
competitive ratio of $k$ applies. If only specific requests appear, a solution
with a competitive ratio of $1$ becomes trivial since there is no freedom regarding
the servers' movements. Perhaps counter-intuitively, we show that if both kinds
of requests appear, the lower bound raises to $2k-1$.\r\n\r\nWe study deterministic
online algorithms in uniform metrics and present two algorithms. The first one
has an adaptive competitive ratio dependent on the frequency of specific requests.
It achieves a worst-case competitive ratio of $3k-2$ while it is optimal when
only general or only specific requests appear (competitive ratio of $k$ and $1$,
respectively). The second has a fixed close-to-optimal worst-case competitive
ratio of $2k+14$. For the first algorithm, we show a lower bound of $3k-2$, while
the second algorithm has a lower bound of $2k-1$ when only general requests appear.\r\n
\ \r\nThe two algorithms differ in only one behavioral rule for each server
that significantly influences the competitive ratio. Each server acting according
to the rule allows approaching the worst-case lower bound, while it implies an
increased lower bound for $k$-Server instances. In other words, there is a trade-off
between performing well against instances of the $k$-Server Problem and instances
containing specific requests. We also show that no deterministic online algorithm
can be optimal for both kinds of instances simultaneously."

text: "Consider the practical goal of making a desired action profile played,\r\n\r\nwhen
the planner can only change the payoffs, bound by \r\n\r\nstringent constraints.\r\n\r\nApplications
include motivating people\r\n\r\nto choose the closest school, the closest subway
station, or to coordinate\r\n\r\non a communication protocol or an investment
strategy.\r\n\r\nEmploying subsidies and tolls, we adjust the game so that choosing
this predefined action profile\r\n\r\nbecomes strictly dominant. \r\n\r\nInspired
mainly by the work of Monderer and Tennenholtz,\r\n\r\nwhere the promised subsidies
do not materialise in the not played\r\n\r\nprofiles, we provide a fair and individually
rational game\r\n\r\nadjustment, such that the total outside investments sum up\r\n\r\nto
zero at any profile, thereby facilitating easy and frequent\r\n\r\nusage of our
adjustment without bearing costs, even if some\r\n\r\nplayers behave unexpectedly.
The resultant action profile itself needs no\r\n\r\nadjustment. Importantly, we
also prove that our adjustment minimises \r\n\r\nthe general transfer among all
such adjustments, counting the total subsidising and taxation."

text: While many research in distributed computing has covered solutions for self-stabilizing
computing and topologies, there is far less work on self-stabilization for distributed
data structures. However, when peers in peer-to-peer networks crash, a distributed
data structure may not remain intact. We present a self-stabilizing protocol for
a distributed data structure called the Hashed Patricia Trie (Kniesburges and
Scheideler WALCOM'11) that enables efficient prefix search on a set of keys. The
data structure has many applications while offering low overhead and efficient
operations when embedded on top of a Distributed Hash Table. Especially, longest
prefix matching for x can be done in O(log |x|) hash table read accesses. We show
how to maintain the structure in a self-stabilizing way, while assuring a low
overhead in a legal state and an asymptotically optimal memory demand of O(d)
bits, where d is the number of bits needed for storing all keys.

text: "Produktentstehung (PE) bezieht sich auf den Prozess der Planung und Entwicklung
eines Produkts sowie der damit verbundenen Dienstleistungen von der ersten Idee
bis zur Herstellung und zum Vertrieb. Während dieses Prozesses gibt es zahlreiche
Aufgaben, die von menschlichem Fachwissen abhängen und typischerweise von erfahrenen
Experten übernommen werden. Da sich das Feld der Künstlichen Intelligenz (KI)
immer weiterentwickelt und seinen Weg in den Fertigungssektor findet, gibt es
viele Möglichkeiten für eine Anwendung von KI, um bei der Lösung der oben genannten
Aufgaben zu helfen. In diesem Paper geben wir einen umfassenden Überblick über
den aktuellen Stand der Technik des Einsatzes von KI in der PE. \r\nIm Detail
analysieren wir 40 bestehende Surveys zu KI in der PE und 94 Case Studies, um
herauszufinden, welche Bereiche der PE von der aktuellen Forschung in diesem Bereich
vorrangig adressiert werden, wie ausgereift die diskutierten KI-Methoden sind
und inwieweit datenzentrierte Ansätze in der aktuellen Forschung genutzt werden."

on human expertise and are typically undertaken by experienced practitioners.
As the field of Artificial Intelligence (AI) continues to evolve and finds its
way into the manufacturing sector, there exist many possibilities for an application
of AI in order to assist in solving aforementioned tasks. In this work, we provide
a comprehensive overview of the current state of the art of the use of AI in PC.
\r\nIn detail, we analyze 40 existing surveys on AI in PC and 94 case studies
in order to find out which areas of PC are primarily addressed by current research
in this field, how mature the discussed AI methods are, and to which extent data-centric

text: 'Over the past decades, the Gathering problem, which asks to gather a group
of robots in finite time given some restrictions, has been intensively studied.
In this paper, we are given a group of n autonomous, dimensionless, deterministic,
and anonymous robots, with bounded viewing range. Assuming a continuous time model,
the goal is to gather these robots into one point in finite time. We introduce
a simple convergence criterion that defines a new class of algorithms which perform
gathering in O(nd) time, where d is the diameter of the initial robot configuration.
We show that some gathering algorithms in the literature belong to this class
and propose two new algorithms that belong to this class and have quadratic running
time, namely, Go-To-The-Relative-Center algorithm (GTRC) and Safe-Go-To-The-Relative-Center
algorithm (S-GTRC). We prove that the latter can perform gathering without collision
by using a slightly more complex robot model: non oblivious, chiral, and luminous
(i.e. robots have observable external memory, as in [8]). We also consider a variant
of the Gathering problem, the Near-Gathering problem, in which robots must get
close to each other without colliding. We show that S-GTRC solves the Near-Gathering
problem in quadratic time and assumes a weaker robot model than the one assumed
in the current state-of-the-art.'

text: "In this paper, we reconsider the well-known discrete, round-based Go-To-The-Center
algorithm due to Ando, Suzuki, and Yamashita [2] for gathering n autonomous mobile
robots with limited viewing range in the plane. Remarquably, this algorithm exploits
the fact that during its execution, many collisions of robots occur. Such collisions
are interpreted as a success because it is assumed that such collided robots behave
the same from now on. This is acceptable under the assumption that each robot
is represented by a single point. Otherwise, collisions should be avoided. In
this paper, we consider a continuous Go-To-The-Center algorithm in which the robots
continuously observe the positions of their neighbors and adapt their speed (assuming
a speed limit) and direction. Our first results are time bounds of O(n2) for gathering
in two dimensions Euclidean space, and Θ(n) for the one dimension. Our main contribution
is the introduction and evaluation of a continuous algorithm which performs Go-To-The-Center
considering only the neighbors of a robot with respect to the Gabriel subgraph
of the visibility graph, i.e. Go-To-The-Gabriel-Center algorithm. We show that
this modification still correctly executes gathering in one and two dimensions,
with the same time bounds as above. Simulations exhibit a severe difference of
the behavior of the Go-To-The-Center and the Go-To-The-Gabriel-Center algorithms:
Whereas lots of collisions occur during a run of the Go-To-The-Center algorithm,
typically only one, namely the final collision occurs during a run of the Go-To-The-Gabriel-Center
algorithm. We can prove this “collisionless property” of the Go-To-The-Gabriel-Center
algorithm for one dimension. In two-dimensional Euclidean space, we conjecture
that the “collisionless property” holds for almost every initial configuration.
We support our conjecture with measurements obtained from the simulation where
robots execute both continuous Go-To-The-Center and Go-To-The-Gabriel-Center algorithms.\r\n"

text: "Consider a set of jobs connected to a directed acyclic task graph with a\r\nfixed
source and sink. The edges of this graph model precedence constraints and\r\nthe
jobs have to be scheduled with respect to those. We introduce the Server\r\nCloud
Scheduling problem, in which the jobs have to be processed either on a\r\nsingle
local machine or on one of many cloud machines. Both the source and the\r\nsink
have to be scheduled on the local machine. For each job, processing times\r\nboth
on the server and in the cloud are given. Furthermore, for each edge in\r\nthe
task graph, a communication delay is included in the input and has to be\r\ntaken
into account if one of the two jobs is scheduled on the server, the other\r\nin
the cloud. The server can process jobs sequentially, whereas the cloud can\r\nserve
as many as needed in parallel, but induces costs. We consider both\r\nmakespan
and cost minimization. The main results are an FPTAS with respect for\r\nthe makespan
objective for a fairly general case and strong hardness for the\r\ncase with unit
processing times and delays."

text: "Most existing robot formation problems seek a target formation of a certain\r\nminimal
and, thus, efficient structure. Examples include the Gathering\r\nand the Chain-Formation
problem. In this work, we study formation problems that\r\ntry to reach a maximal
structure, supporting for example an efficient\r\ncoverage in exploration scenarios.
A recent example is the NASA Shapeshifter\r\nproject, which describes how the
robots form a relay chain along which gathered\r\ndata from extraterrestrial cave
explorations may be sent to a home base.\r\n As a first step towards understanding
such maximization tasks, we introduce\r\nand study the Max-Chain-Formation problem,
where $n$ robots are ordered along a\r\nwinding, potentially self-intersecting
chain and must form a connected,\r\nstraight line of maximal length connecting
its two endpoints. We propose and\r\nanalyze strategies in a discrete and in a
continuous time model. In the\r\ndiscrete case, we give a complete analysis if
all robots are initially\r\ncollinear, showing that the worst-case time to reach
an\r\n$\\varepsilon$-approximation is upper bounded by $\\mathcal{O}(n^2 \\cdot
\\log\r\n(n/\\varepsilon))$ and lower bounded by $\\Omega(n^2 \\cdot~\\log\r\n(1/\\varepsilon))$.
If one endpoint of the chain remains stationary, this result\r\ncan be extended
to the non-collinear case. If both endpoints move, we identify\r\na family of
instances whose runtime is unbounded. For the continuous model, we\r\ngive a strategy
with an optimal runtime bound of $\\Theta(n)$. Avoiding an\r\nunbounded runtime
similar to the discrete case relies crucially on a\r\ncounter-intuitive aspect
of the strategy: slowing down the endpoints while all\r\nother robots move at
full speed. Surprisingly, we can show that a similar trick\r\ndoes not work in
the discrete model."

text: "Let G = (V,E) be an undirected graph on n vertices with non-negative capacities
on its edges. The mincut sensitivity problem for the insertion of an edge is defined
as follows. Build a compact data structure for G and a given set S ⊆ V of vertices
that, on receiving any edge (x,y) ∈ S×S of positive capacity as query input, can
efficiently report the set of all pairs from S× S whose mincut value increases
upon insertion of the edge (x,y) to G. The only result that exists for this problem
is for a single pair of vertices (Picard and Queyranne, Mathematical Programming
Study, 13 (1980), 8-16). We present the following results for the single source
and the all-pairs versions of this problem. \r\n1) Single source: Given any designated
source vertex s, there exists a data structure of size \U0001D4AA(|S|) that can
output all those vertices from S whose mincut value to s increases upon insertion
of any given edge. The time taken by the data structure to answer any query is
\U0001D4AA(|S|). \r\n2) All-pairs: There exists an \U0001D4AA(|S|²) size data
structure that can output all those pairs of vertices from S× S whose mincut value
gets increased upon insertion of any given edge. The time taken by the data structure
to answer any query is \U0001D4AA(k), where k is the number of pairs of vertices
whose mincut increases. \r\nFor both these versions, we also address the problem
of reporting the values of the mincuts upon insertion of any given edge. To derive
our results, we use interesting insights into the nearest and the farthest mincuts
for a pair of vertices. In addition, a crucial result, that we establish and use
in our data structures, is that there exists a directed acyclic graph of \U0001D4AA(n)
size that compactly stores the farthest mincuts from all vertices of V to a designated
vertex s in the graph. We believe that this result is of independent interest,
especially, because it also complements a previously existing result by Hariharan
et al. (STOC 2007) that the nearest mincuts from all vertices of V to s is a laminar
family, and hence, can be stored compactly in a tree of \U0001D4AA(n) size."

text: " We consider a natural extension to the metric uncapacitated Facility Location
Problem (FLP) in which requests ask for different commodities out of a finite
set \\( S \\) of commodities.\r\n Ravi and Sinha (SODA 2004) introduced the model
as the \\emph{Multi-Commodity Facility Location Problem} (MFLP) and considered
it an offline optimization problem.\r\n The model itself is similar to the FLP:
i.e., requests are located at points of a finite metric space and the task of
an algorithm is to construct facilities and assign requests to facilities while
minimizing the construction cost and the sum over all assignment distances.\r\n
\ In addition, requests and facilities are heterogeneous; they request or offer
multiple commodities out of $S$.\r\n A request has to be connected to a set of
facilities jointly offering the commodities demanded by it.\r\n In comparison
to the FLP, an algorithm has to decide not only if and where to place facilities,
but also which commodities to offer at each.\r\n\r\n To the best of our knowledge
we are the first to study the problem in its online variant in which requests,
their positions and their commodities are not known beforehand but revealed over
time.\r\n We present results regarding the competitive ratio.\r\n On the one
hand, we show that heterogeneity influences the competitive ratio by developing
a lower bound on the competitive ratio for any randomized online algorithm of
\\( \\Omega ( \\sqrt{|S|} + \\frac{\\log n}{\\log \\log n} ) \\) that already
holds for simple line metrics.\r\n Here, \\( n \\) is the number of requests.\r\n
\ On the other side, we establish a deterministic \\( \\mathcal{O}(\\sqrt{|S|}
\\cdot \\log n) \\)-competitive algorithm and a randomized \\( \\mathcal{O}(\\sqrt{|S|}
\\cdot \\frac{\\log n}{\\log \\log n} ) \\)-competitive algorithm.\r\n Further,
we show that when considering a more special class of cost functions for the construction
cost of a facility, the competitive ratio decreases given by our deterministic
algorithm depending on the function."

text: "In this work, we initiate the research about the Gathering problem for robots\r\nwith
limited viewing range in the three-dimensional Euclidean space. In the\r\nGathering
problem, a set of initially scattered robots is required to gather at\r\nthe same
position. The robots' capabilities are very restricted -- they do not\r\nagree
on any coordinate system or compass, have a limited viewing range, have\r\nno
memory of the past and cannot communicate. We study the problem in two\r\ndifferent
time models, in FSYNC (fully synchronized discrete rounds) and the\r\ncontinuous
time model. For FSYNC, we introduce the 3D-Go-To-The-Center-strategy\r\nand prove
a runtime of $\\Theta(n^2)$ that matches the currently best runtime\r\nbound for
the same model in the Euclidean plane [SPAA'11]. Our main result is\r\nthe generalization
of contracting strategies (continuous time) from\r\n[Algosensors'17] to three
dimensions. In contracting strategies, every robot\r\nthat is located on the global
convex hull of all robots' positions moves with\r\nfull speed towards the inside
of the convex hull. We prove a runtime bound of\r\n$O(\\Delta \\cdot n^{3/2})$
for any three-dimensional contracting strategy, where\r\n$\\Delta$ denotes the
diameter of the initial configuration. This comes up to a\r\nfactor of $\\sqrt{n}$
close to the lower bound of $\\Omega (\\Delta \\cdot n)$\r\nwhich is already true
in two dimensions. In general, it might be hard for\r\nrobots with limited viewing
range to decide whether they are located on the\r\nglobal convex hull and which
movement maintains the connectivity of the swarm,\r\nrendering the design of concrete
contracting strategies a challenging task. We\r\nprove that the continuous variant
of 3D-Go-To-The-Center is contracting and\r\nkeeps the swarm connected. Moreover,
we give a simple design criterion for\r\nthree-dimensional contracting strategies
that maintains the connectivity of the\r\nswarm and introduce an exemplary strategy
based on this criterion."

text: In software engineering, the imprecise requirements of a user are transformed
to a formal requirements specification during the requirements elicitation process.
This process is usually guided by requirements engineers interviewing the user.
We want to partially automate this first step of the software engineering process
in order to enable users to specify a desired software system on their own. With
our approach, users are only asked to provide exemplary behavioral descriptions.
The problem of synthesizing a requirements specification from examples can partially
be reduced to the problem of grammatical inference, to which we apply an active
coevolutionary learning approach. However, this approach would usually require
many feedback queries to be sent to the user. In this work, we extend and generalize
our active learning approach to receive knowledge from multiple oracles, also
known as proactive learning. The ‘user oracle’ represents input received from
the user and the ‘knowledge oracle’ represents available, formalized domain knowledge.
We call our two-oracle approach the ‘first apply knowledge then query’ (FAKT/Q)
algorithm. We compare FAKT/Q to the active learning approach and provide an extensive
benchmark evaluation. As result we find that the number of required user queries
is reduced and the inference process is sped up significantly. Finally, with so-called
On-The-Fly Markets, we present a motivation and an application of our approach
where such knowledge is available.

text: 'Resolving distributed attacks benefits from collaboration between networks.
We present three approaches for the same multi-domain defensive action that can
be applied in such an alliance: 1) Counteract Everywhere, 2) Minimize Countermeasures,
and 3) Minimize Propagation. First, we provide a formula to compute efficiency
of a defense; then we use this formula to compute the efficiency of the approaches
under various circumstances. Finally, we discuss how task execution order and
timing influence defense efficiency. Our results show that the Minimize Propagation
approach is the most efficient method when defending against the chosen attack.'

text: This thesis investigates approximate pure Nash equilibria in different game-theoretic
models. In such an outcome, no player can improve her objective by more than a
given factor through a deviation to another strategy. In the first part, we investigate
two variants of Congestion Games in which the existence of pure Nash equilibria
is guaranteed through a potential function argument. However, the computation
of such equilibria might be hard. We construct and analyze approximation algorithms
that enable the computation of states with low approximation factors in polynomial
time. To show their guarantees we use sub games among players, bound the potential
function values of arbitrary states and exploit a connection between Shapley and
proportional cost shares. Furthermore, we apply and analyze sampling techniques
for the computation of approximate Shapley values in different settings. In the
second part, we concentrate on the existence of approximate pure Nash equilibria
in games in which no pure Nash equilibria exist in general. In the model of Coevolving
Opinion Formation Games, we bound the approximation guarantees for natural states
nearly independent of the specific definition of the players' neighborhoods by
applying a concept of virtual costs. For the special case of only one influential
neighbor, we even show lower approximation factors for a natural strategy. Then,
we investigate a two-sided Facility Location Game among facilities and clients
on a line with an objective function consisting of distance and load. We show
tight bounds on the approximation factor for settings with three facilities and
infinitely many clients. For the general scenario with an arbitrary number of
facilities, we bound the approximation factor for two promising candidates, namely
facilities that are uniformly distributed and which are paired.

text: "We characterise the set of dominant strategy incentive compatible (DSIC),
strongly budget balanced (SBB), and ex-post individually rational (IR) mechanisms
for the multi-unit bilateral trade setting. In such a setting there is a single
buyer and a single seller who holds a finite number k of identical items. The
mechanism has to decide how many units of the item are transferred from the seller
to the buyer and how much money is transferred from the buyer to the seller. We
consider two classes of valuation functions for the buyer and seller: Valuations
that are increasing in the number of units in possession, and the more specific
class of valuations that are increasing and submodular. \r\nFurthermore, we present
some approximation results about the performance of certain such mechanisms, in
terms of social welfare: For increasing submodular valuation functions, we show
the existence of a deterministic 2-approximation mechanism and a randomised e/(1-e)
approximation mechanism, matching the best known bounds for the single-item setting."

text: "We present a technique for rendering highly complex 3D scenes in real-time
by\r\ngenerating uniformly distributed points on the scene's visible surfaces.
The\r\ntechnique is applicable to a wide range of scene types, like scenes directly\r\nbased
on complex and detailed CAD data consisting of billions of polygons (in\r\ncontrast
to scenes handcrafted solely for visualization). This allows to\r\nvisualize such
scenes smoothly even in VR on a HMD with good image quality,\r\nwhile maintaining
the necessary frame-rates. In contrast to other point based\r\nrendering methods,
we place points in an approximated blue noise distribution\r\nonly on visible
surfaces and store them in a highly GPU efficient data\r\nstructure, allowing
to progressively refine the number of rendered points to\r\nmaximize the image
quality for a given target frame rate. Our evaluation shows\r\nthat scenes consisting
of a high amount of polygons can be rendered with\r\ninteractive frame rates with
good visual quality on standard hardware."

text: 'Competing firms tend to select similar locations for their stores. This phenomenon,
called the principle of minimum differentiation, was captured by Hotelling with
a landmark model of spatial competition but is still the object of an ongoing
scientific debate. Although consistently observed in practice, many more realistic
variants of Hotelling''s model fail to support minimum differentiation or do not
have pure equilibria at all. In particular, it was recently proven for a generalized
model which incorporates negative network externalities and which contains Hotelling''s
model and classical selfish load balancing as special cases, that the unique equilibria
do not adhere to minimum differentiation. Furthermore, it was shown that for a
significant parameter range pure equilibria do not exist. We derive a sharp contrast
to these previous results by investigating Hotelling''s model with negative network
externalities from an entirely new angle: approximate pure subgame perfect equilibria.
This approach allows us to prove analytically and via agent-based simulations
that approximate equilibria having good approximation guarantees and that adhere
to minimum differentiation exist for the full parameter range of the model. Moreover,
we show that the obtained approximate equilibria have high social welfare.'

text: We study the classic bin packing problem in a fully-dynamic setting, where
new items can arrive and old items may depart. We want algorithms with low asymptotic
competitive ratio while repacking items sparingly between updates. Formally, each
item i has a movement cost c_i >= 0, and we want to use alpha * OPT bins and incur
a movement cost gamma * c_i, either in the worst case, or in an amortized sense,
for alpha, gamma as small as possible. We call gamma the recourse of the algorithm.
This is motivated by cloud storage applications, where fully-dynamic bin packing
models the problem of data backup to minimize the number of disks used, as well
as communication incurred in moving file backups between disks. Since the set
of files changes over time, we could recompute a solution periodically from scratch,
but this would give a high number of disk rewrites, incurring a high energy cost
and possible wear and tear of the disks. In this work, we present optimal tradeoffs
between number of bins used and number of items repacked, as well as natural extensions
of the latter measure.

text: We consider a group of $n$ autonomous mobile robots of which $m$ are stationary
thus cannot move. Robots are represented by points in the Euclidean plane. They
have no memory, do not communicate or share a common coordinate system and they
move solely based on the positioning of other robots within their limited viewing
range of 1. The goal is to gather the robots inside of the convex hull of all
stationary robots. A variant of this problem, the general gathering problem, has
been studied in various different time models. In this work, we consider a continuous
time model, where robots continuously observe their neighbors, compute the next
target of movement and move with a speed limit of 1 at any time. Regarding the
robots' local strategy, we only study contracting algorithms in which every robot
that is positioned on the border of the convex hull of all robots moves into this
hull. We present a time bound of $\mathcal{O}(nd)$ for any general contracting
algorithms in a configuration with only a single stationary robot. For configurations
with more stationary robots, we prove that robots converge against the convex
hull of all stationary robots and that no upper bound on the runtime exists. For
the specific contracting algorithms Go-To-The-Left, Go-On-Bisector and Go-To-The-Middle,
we provide linear time bounds.

text: "We introduce the \\emph{Online Connected Dominating Set Leasing} problem\r\n(OCDSL)
in which we are given an undirected connected graph $G = (V, E)$, a set\r\n$\\mathcal{L}$
of lease types each characterized by a duration and cost, and a\r\nsequence of
subsets of $V$ arriving over time. A node can be leased using lease\r\ntype $l$
for cost $c_l$ and remains active for time $d_l$. The adversary gives\r\nin each
step $t$ a subset of nodes that need to be dominated by a connected\r\nsubgraph
consisting of nodes active at time $t$. The goal is to minimize the\r\ntotal leasing
costs. OCDSL contains the \\emph{Parking Permit\r\nProblem}~\\cite{PPP} as a special
subcase and generalizes the classical offline\r\n\\emph{Connected Dominating Set}
problem~\\cite{Guha1998}. It has an $\\Omega(\\log\r\n^2 n + \\log |\\mathcal{L}|)$
randomized lower bound resulting from lower bounds\r\nfor the \\emph{Parking Permit
Problem} and the \\emph{Online Set Cover}\r\nproblem~\\cite{Alon:2003:OSC:780542.780558,Korman},
where $|\\mathcal{L}|$ is the\r\nnumber of available lease types and $n$ is the
number of nodes in the input\r\ngraph. We give a randomized $\\mathcal{O}(\\log
^2 n + \\log |\\mathcal{L}| \\log\r\nn)$-competitive algorithm for OCDSL. We also
give a deterministic algorithm for\r\na variant of OCDSL in which the dominating
subgraph need not be connected, the\r\n\\emph{Online Dominating Set Leasing} problem.
The latter is based on a simple\r\nprimal-dual approach and has an $\\mathcal{O}(|\\mathcal{L}|
\\cdot\r\n\\Delta)$-competitive ratio, where $\\Delta$ is the maximum degree of
the input\r\ngraph."

text: 'We consider a market where final products or services are compositions of
a number of basic services. Users are asked to evaluate the quality of the composed
product after purchase. The quality of the basic service influences the performance
of the composed services but cannot be observed directly. The question we pose
is whether it is possible to use user evaluations on composed services to assess
the quality of basic services. We discuss how to combine aggregation of evaluations
across users and disaggregation of information on composed services to derive
valuations for the single components. As a solution we propose to use the (weighted)
average as aggregation device in connection with the Shapley value as disaggregation
method, since this combination fulfills natural requirements in our context. In
addition, we address some occurring computational issues: We give an approximate
solution concept using only a limited number of evaluations which guarantees nearly
optimal results with reduced running time. Lastly, we show that a slightly modified
Shapley value and the weighted average are still applicable if the evaluation
profiles are incomplete.'

text: 'We study the Online Prize-collecting Node-weighted Steiner Forest problem
(OPC-NWSF) in which we are given an undirected graph \(G=(V, E)\) with \(|V| =
n\) and node-weight function \(w: V \rightarrow \mathcal {R}^+\). A sequence of
k pairs of nodes of G, each associated with a penalty, arrives online. OPC-NWSF
asks to construct a subgraph H such that each pair \(\{s, t\}\) is either connected
(there is a path between s and t in H) or its associated penalty is paid. The
goal is to minimize the weight of H and the total penalties paid. The current
best result for OPC-NWSF is a randomized \(\mathcal {O}(\log ^4 n)\)-competitive
algorithm due to Hajiaghayi et al. (ICALP 2014). We improve this by proposing
a randomized \(\mathcal {O}(\log n \log k)\)-competitive algorithm for OPC-NWSF,
which is optimal up to constant factor since OPC-NWSF has a randomized lower bound
of \(\varOmega (\log ^2 n)\) due to Korman [11]. Moreover, our result also implies
an improvement for two special cases of OPC-NWSF, the Online Prize-collecting
Node-weighted Steiner Tree problem (OPC-NWST) and the Online Node-weighted Steiner
Forest problem (ONWSF). In OPC-NWST, there is a distinguished node which is one
of the nodes in each pair. In ONWSF, all penalties are set to infinity. The currently
best known results for OPC-NWST and ONWSF are a randomized \(\mathcal {O}(\log
^3 n)\)-competitive algorithm due to Hajiaghayi et al. (ICALP 2014) and a randomized
\(\mathcal {O}(\log n \log ^2 k)\)-competitive algorithm due to Hajiaghayi et
al. (FOCS 2013), respectively.'

text: 'Consider mitigating the effects of denial of service or of malicious traffic
in networks by deleting edges. Edge deletion reduces the DoS or the number of
the malicious flows, but it also inadvertently removes some of the desired flows.
To model this important problem, we formulate two problems: (1) remove all the
undesirable flows while minimizing the damage to the desirable ones and (2) balance
removing the undesirable flows and not removing too many of the desirable flows.
We prove these problems are equivalent to important theoretical problems, thereby
being important not only practically but also theoretically, and very hard to
approximate in a general network. We employ reductions to nonetheless approximate
the problem and also provide a greedy approximation. When the network is a tree,
the problems are still MAX SNP-hard, but we provide a greedy-based 2l-approximation
algorithm, where l is the longest desirable flow. We also provide an algorithm,
approximating the first and the second problem within {\$}{\$}2 {\backslash}sqrt{\{}
2{\backslash}left| E {\backslash}right| {\}}{\$}{\$}and {\$}{\$}2 {\backslash}sqrt{\{}2
({\backslash}left| E {\backslash}right| + {\backslash}left| {\backslash}text {\{}undesirable
flows{\}} {\backslash}right| ){\}}{\$}{\$}, respectively, where E is the set of
the edges of the network. We also provide a fixed-parameter tractable (FPT) algorithm.
Finally, if the tree has a root such that every flow in the tree flows on the
path from the root to a leaf, we solve the problem exactly using dynamic programming.'

text: 'Software Defined Networks (SDN) and Network Function Virtualisation (NFV)
provide the basis for autonomous response and mitigation against attacks on networked
computer infrastructures. We propose a new framework that uses SDNs and NFV to
achieve this goal: Secure Autonomous Response Network (SARNET). In a SARNET, an
agent running a control loop constantly assesses the security state of the network
by means of observables. The agent reacts to and resolves security problems, while
learning from its previous decisions. Two main metrics govern the decision process
in a SARNET: impact and efficiency; these metrics can be used to compare and evaluate
countermeasures and are the building blocks for self-learning SARNETs that exhibit
autonomous response. In this paper we present the software implementation of the
SARNET framework, evaluate it in a real-life network and discuss the tradeoffs
between parameters used by the SARNET agent and the efficiency of its actions.'

text: "While a lot of research in distributed computing has covered solutions for
self-stabilizing computing and topologies, there is far less work on self-stabilization
for distributed data structures.\r\nConsidering crashing peers in peer-to-peer
networks, it should not be taken for granted that a distributed data structure
remains intact.\r\nIn this work, we present a self-stabilizing protocol for a
distributed data structure called the hashed Patricia Trie (Kniesburges and Scheideler
WALCOM'11) that enables efficient prefix search on a set of keys.\r\nThe data
structure has a wide area of applications including string matching problems while
offering low overhead and efficient operations when embedded on top of a distributed
hash table.\r\nEspecially, longest prefix matching for $x$ can be done in $\\mathcal{O}(\\log
|x|)$ hash table read accesses.\r\nWe show how to maintain the structure in a
self-stabilizing way.\r\nOur protocol assures low overhead in a legal state and
a total (asymptotically optimal) memory demand of $\\Theta(d)$ bits, where $d$
is the number of bits needed for storing all keys."

text: "Routing is a challenging problem for wireless ad hoc networks, especially
when the nodes are mobile and spread so widely that in most cases multiple hops
are needed to route a message from one node to another. In fact, it is known that
any online routing protocol has a poor performance in the worst case, in a sense
that there is a distribution of nodes resulting in bad routing paths for that
protocol, even if the nodes know their geographic positions and the geographic
position of the destination of a message is known. The reason for that is that
radio holes in the ad hoc network may require messages to take long detours in
order to get to a destination, which are hard to find in an online fashion.\r\n\r\nIn
this paper, we assume that the wireless ad hoc network can make limited use of
long-range links provided by a global communication infrastructure like a cellular
infrastructure or a satellite in order to compute an abstraction of the wireless
ad hoc network that allows the messages to be sent along near-shortest paths in
the ad hoc network. We present distributed algorithms that compute an abstraction
of the ad hoc network in $\\mathcal{O}\\left(\\log ^2 n\\right)$ time using long-range
links, which results in $c$-competitive routing paths between any two nodes of
the ad hoc network for some constant $c$ if the convex hulls of the radio holes
do not intersect. We also show that the storage needed for the abstraction just
depends on the number and size of the radio holes in the wireless ad hoc network
and is independent on the total number of nodes, and this information just has
to be known to a few nodes for the routing to work.\r\n"

text: "We present a peer-to-peer network that supports the efficient processing
of orthogonal range queries $R=\\bigtimes_{i=1}^{d}[a_i,\\,b_i]$ in a $d$-dimensional
point space.\\\\\r\nThe network is the same for each dimension, namely a distance
halving network like the one introduced by Naor and Wieder (ACM TALG'07).\r\nWe
show how to execute such range queries using $\\mathcal{O}\\left(2^{d'}d\\,\\log
m + d\\,|R|\\right)$ hops (and the same number of messages) in total. Here $[m]^d$
is the ground set, $|R|$ is the size and $d'$ the dimension of the queried range.\r\nFurthermore,
if the peers form a distributed network, the query can be answered in $\\mathcal{O}\\left(d\\,\\log
m + d\\,\\sum_{i=1}^{d}(b_i-a_i+1)\\right)$ communication rounds.\r\nOur algorithms
are based on a mapping of the Hilbert Curve through $[m]^d$ to the peers."

text: We study a new class of games which generalizes congestion games andits bottleneck
variant. We introduce congestion games with mixed objectives to modelnetwork scenarios
in which players seek to optimize for latency and bandwidths alike.We characterize
the (non-)existence of pure Nash equilibria (PNE), the convergenceof improvement
dynamics, the quality of equilibria and show the complexity of thedecision problem.
For games that do not possess PNE we give bounds on the approx-imation ratio of
approximate pure Nash equilibria.

text: 'My dissertation deals with the Gathering problem for swarms of n point-shaped
robots on a grid, in which all robots of the swarm are supposed to gather at a
previously undefined point. Special attention is paid to the strong limitation
of robot capabilities. These include in particular the lack of global control,
a global compass, global visibility and (global) communication skills. Furthermore,
all robots are identical. The robots are given only local abilities. This includes
a constant range of vision. The robots all work completely synchronously. In this
work we present and analyze three different Gathering strategies in different
robot models. We formally prove correctness and total running time: Chapter 4
focuses on minimizing the available robot capabilities. The underlying strategy
completes the gathering in O(n^2) time. For the following Chapters 5 and 6, the
aim is to optimize the total running time under using only local robot capabilities:
We additionally allow a constant-sized memory and a constant number of locally
visible statuses (lights, flags). For the strategies of both chapters we show
an asymptotically optimal running time of O(n). Unlike in Chapters 4 and 5, we
additionally restrict connectivity and vision to an initially given chain connectivity
in Chapter 6, where two chain neighbors must have a distance of 1 from each other.
A robot can only see and interact with a constant number of its direct chain neighbors.'

text: In budget games, players compete over resources with finite budgets. For every
resource, a player has a specific demand and as a strategy, he chooses a subset
of resources. If the total demand on a resource does not exceed its budget, the
utility of each player who chose that resource equals his demand. Otherwise, the
budget is shared proportionally. In the general case, pure Nash equilibria (NE)
do not exist for such games. In this paper, we consider the natural classes of
singleton and matroid budget games with additional constraints and show that for
each, pure NE can be guaranteed. In addition, we introduce a lexicographical potential
function to prove that every matroid budget game has an approximate pure NE which
depends on the largest ratio between the different demands of each individual
player.

text: 'Through this study, we introduce the idea of applying scheduling techniques
to allocate spatial resources that are shared among multiple robots moving in
a static environment and having temporal constraints on the arrival time to destinations.
To illustrate this idea, we present an exemplified algorithm that plans and assigns
a motion path to each robot. The considered problem is particularly challenging
because: (i) the robots share the same environment and thus the planner must take
into account overlapping paths which cannot happen at the same time; (ii) there
are time deadlines thus the planner must deal with temporal constraints; (iii)
new requests arrive without a priori knowledge thus the planner must be able to
add new paths online and adjust old plans; (iv) the robot motion is subject to
noise thus the planner must be reactive to adapt to online changes. We showcase
the functioning of the proposed algorithm through a set of agent-based simulations.'

text: We study a model of selfish resource allocation that seeks to incorporate
dependencies among resources as they exist in in modern networked environments.
Our model is inspired by utility functions with constant elasticity of substitution
(CES) which is a well-studied model in economics. We consider congestion games
with different aggregation functions. In particular, we study $L_p$ norms and
analyze the existence and complexity of (approximate) pure Nash equilibria. Additionally,
we give an almost tight characterization based on monotonicity properties to describe
the set of aggregation functions that guarantee the existence of pure Nash equilibria.

text: We study the computation of approximate pure Nash equilibria in Shapley value
(SV) weighted congestion games, introduced in [19]. This class of games considers
weighted congestion games in which Shapley values are used as an alternative (to
proportional shares) for distributing the total cost of each resource among its
users. We focus on the interesting subclass of such games with polynomial resource
cost functions and present an algorithm that computes approximate pure Nash equilibria
with a polynomial number of strategy updates. Since computing a single strategy
update is hard, we apply sampling techniques which allow us to achieve polynomial
running time. The algorithm builds on the algorithmic ideas of [7], however, to
the best of our knowledge, this is the first algorithmic result on computation
of approximate equilibria using other than proportional shares as player costs
in this setting. We present a novel relation that approximates the Shapley value
of a player by her proportional share and vice versa. As side results, we upper
bound the approximate price of anarchy of such games and significantly improve
the best known factor for computing approximate pure Nash equilibria in weighted
congestion games of [7].

text: "We consider a swarm of $n$ autonomous mobile robots, distributed on a\r\n2-dimensional
grid. A basic task for such a swarm is the gathering process: All\r\nrobots have
to gather at one (not predefined) place. A common local model for\r\nextremely
simple robots is the following: The robots do not have a common\r\ncompass, only
have a constant viewing radius, are autonomous and\r\nindistinguishable, can move
at most a constant distance in each step, cannot\r\ncommunicate, are oblivious
and do not have flags or states. The only gathering\r\nalgorithm under this robot
model, with known runtime bounds, needs\r\n$\\mathcal{O}(n^2)$ rounds and works
in the Euclidean plane. The underlying time\r\nmodel for the algorithm is the
fully synchronous $\\mathcal{FSYNC}$ model. On\r\nthe other side, in the case
of the 2-dimensional grid, the only known gathering\r\nalgorithms for the same
time and a similar local model additionally require a\r\nconstant memory, states
and \"flags\" to communicate these states to neighbors in\r\nviewing range. They
gather in time $\\mathcal{O}(n)$.\r\n In this paper we contribute the (to the
best of our knowledge) first\r\ngathering algorithm on the grid that works under
the same simple local model as\r\nthe above mentioned Euclidean plane strategy,
i.e., without memory (oblivious),\r\n\"flags\" and states. We prove its correctness
and an $\\mathcal{O}(n^2)$ time\r\nbound in the fully synchronous $\\mathcal{FSYNC}$
time model. This time bound\r\nmatches the time bound of the best known algorithm
for the Euclidean plane\r\nmentioned above. We say gathering is done if all robots
are located within a\r\n$2\\times 2$ square, because in $\\mathcal{FSYNC}$ such
configurations cannot be\r\nsolved."

text: Consider a problem in which $n$ jobs that are classified into $k$ types arrive
over time at their release times and are to be scheduled on a single machine so
as to minimize the maximum flow time.The machine requires a setup taking $s$ time
units whenever it switches from processing jobs of one type to jobs of a different
type.We consider the problem as an online problem where each job is only known
to the scheduler as soon as it arrives and where the processing time of a job
only becomes known upon its completion (non-clairvoyance).We are interested in
the potential of simple ``greedy-like'' algorithms.We analyze a modification of
the FIFO strategy and show its competitiveness to be $\Theta(\sqrt{n})$, which
is optimal for the considered class of algorithms.For $k=2$ types it achieves
a constant competitiveness.Our main insight is obtained by an analysis of the
smoothed competitiveness.If processing times $p_j$ are independently perturbed
to $\hat p_j = (1+X_j)p_j$, we obtain a competitiveness of $O(\sigma^{-2} \log^2
n)$ when $X_j$ is drawn from a uniform or a (truncated) normal distribution with
standard deviation $\sigma$.The result proves that bad instances are fragile and
``practically'' one might expect a much better performance than given by the $\Omega(\sqrt{n})$-bound.

text: Many graph problems such as maximum cut, chromatic number, hamiltonian cycle,
and edge dominating set are known to be fixed-parameter tractable (FPT) when parameterized
by the treewidth of the input graphs, but become W-hard with respect to the clique-width
parameter. Recently, Gajarský et al. proposed a new parameter called modular-width
using the notion of modular decomposition of graphs. They showed that the chromatic
number problem and the partitioning into paths problem, and hence hamiltonian
path and hamiltonian cycle, are FPT when parameterized by this parameter. In this
paper, we study modular-width in parameterized parallel complexity and show that
the weighted maximum clique problem and the maximum matching problem are fixed-parameter
parallel-tractable (FPPT) when parameterized by this parameter.

text: We consider a scheduling problem on $m$ identical processors sharing an arbitrarily
divisible resource. In addition to assigning jobs to processors, the scheduler
must distribute the resource among the processors (e.g., for three processors
in shares of 20\%, 15\%, and 65\%) and adjust this distribution over time. Each
job $j$ comes with a size $p_j \in \mathbb{R}$ and a resource requirement $r_j
> 0$. Jobs do not benefit when receiving a share larger than $r_j$ of the resource.
But providing them with a fraction of the resource requirement causes a linear
decrease in the processing efficiency. We seek a (non-preemptive) job and resource
assignment minimizing the makespan.Our main result is an efficient approximation
algorithm which achieves an approximation ratio of $2 + 1/(m-2)$. It can be improved
to an (asymptotic) ratio of $1 + 1/(m-1)$ if all jobs have unit size. Our algorithms
also imply new results for a well-known bin packing problem with splittable items
and a restricted number of allowed item parts per bin.Based upon the above solution,
we also derive an approximation algorithm with similar guarantees for a setting
in which we introduce so-called tasks each containing several jobs and where we
are interested in the average completion time of tasks (a task is completed when
all its jobs are completed).
