text: 'We present three robust overlay networks: First, we present a network that
organizes the nodes into an expander and is resistant to even massive adversarial
churn. Second, we develop a network based on the hypercube that maintains connectivity
under adversarial DoS-attacks. For the DoS-attacks we use the notion of a Omega(log
log n)-late adversary which only has access to topological information that is
at least Omega(log log n) rounds old. Finally, we develop a network that combines
both churn- and DoS-resistance. The networks gain their robustness through constant
network reconfiguration, i.e., the topology of the networks changes constantly.
Our reconguration algorithms are based on node sampling primitives for expanders
and hypercubes that allow each node to sample a logarithmic number of nodes uniformly
at random in O(log log n) communication rounds. These primitives are specific
to overlay networks and their optimal runtime represents an exponential improvement
over known techniques. Our results have a wide range of applications, for example
in the area of scalable and robust peer-to-peer systems.'

text: 'Efficiently parallelizable parameterized problems have been classified as
being either in the class FPP (fixed-parameter parallelizable) or the class PNC
(parameterized analog of NC), which contains FPP as a subclass. In this paper,
we propose a more restrictive class of parallelizable parameterized problems called
fixed-parameter parallel-tractable (FPPT). For a problem to be in FPPT, it should
possess an efficient parallel algorithm not only from a theoretical standpoint
but in practice as well. The primary distinction between FPPT and FPP is the parallel
processor utilization, which is bounded by a polynomial function in the case of
FPPT. We initiate the study of FPPT with the well-known k-vertex cover problem.
In particular, we present a parallel algorithm that outperforms the best known
parallel algorithm for this problem: using O(m) instead of O(n2) parallel processors,
the running time improves from 4logn+O(kk) to O(k⋅log3n), where m is the number
of edges, n is the number of vertices of the input graph, and k is an upper bound
of the size of the sought vertex cover. We also note that a few P-complete problems
fall into FPPT including the monotone circuit value problem (MCV) when the underlying
graphs are bounded by a constant Euler genus.'

text: We consider a scheduling problem where machines need to be rented from the
cloud in order to process jobs. There are two types of machines available which
can be rented for machine-type dependent prices and for arbitrary durations. However,
a machine-type dependent setup time is required before a machine is available
for processing. Jobs arrive online over time, have machine-type dependent sizes
and have individual deadlines. The objective is to rent machines and schedule
jobs so as to meet all deadlines while minimizing the rental cost. Since we observe
the slack of jobs to have a fundamental influence on the competitiveness, we study
the model when instances are parameterized by their (minimum) slack. An instance
is called to have a slack of $\beta$ if, for all jobs, the difference between
the job's release time and the latest point in time at which it needs to be started
is at least $\beta$. While for $\beta series = {LNCS}

scenarios in which players seek to optimize for latency and bandwidths alike.
We characterize the existence of pure Nash equilibria (PNE) and the convergence
of improvement dynamics. For games that do not possess PNE we give bounds on the
approximation ratio of approximate pure Nash equilibria.

text: "In this paper, we solve the local gathering problem of a swarm of $n$\r\nindistinguishable,
point-shaped robots on a two dimensional grid in\r\nasymptotically optimal time
$\\mathcal{O}(n)$ in the fully synchronous\r\n$\\mathcal{FSYNC}$ time model. 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 $\\mathcal{O}(n^2)$."

text: We apply methods of genetic programming to a general problem from software
engineering, namely example-based generation of specifications. 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.

text: Consider a scheduling problem in which a set of jobs with interjob communication,
canonically represented by a weighted tree, needs to be scheduled on m parallel
processors interconnected by a shared communication channel. In each time step,
we may allow any processed job to use a certain capacity of the channel in order
to satisfy (parts of) its communication demands to adjacent jobs processed in
parallel. The goal is to find a schedule that minimizes the makespan and in which
communication demands of all jobs are satisfied.We show that this problem is NP-hard
in the strong sense even if the number of processors and the maximum degree of
the underlying tree is constant.Consequently, we design and analyze simple approximation
algorithms with asymptotic approximation ratio 2-2/m in case of paths and a ratio
of 5/2 in case of arbitrary trees.

text: Abstract—Max-min fairness (MMF) is a widely known approachto a fair allocation
of bandwidth to each of the usersin a network. This allocation can be computed
by uniformlyraising the bandwidths of all users without violating capacityconstraints.
We consider an extension of these allocations byraising the bandwidth with arbitrary
and not necessarily uniformtime-depending velocities (allocation rates). 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. In addition, weshow that when a designer can
adjust allocation rates, it is possibleto design games with optimal strong equilibria.
Some initial resultson polynomial-time algorithms in this direction are also derived.

text: 'In this paper we consider a strategic variant of the online facility location
problem. 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).'

text: "Defining, measuring, and comparing the quality and efficiency of rendering
algorithms in computer graphics is a demanding challenge: quality measures are
often application specific and efficiency is strongly influenced by properties
of the rendered scene and the used hardware. We survey the currently employed
evaluation methods for AQ1 the development process of rendering algorithms. Then,
we present our PADrend framework, which supports systematic and flexible development,
evaluation, adaptation, and comparison of rendering algorithms, and provides a
comfortable and easy-to-use platform for developers of rendering algorithms. The
system includes a new evaluation method to improve the objectivity of experimental

text: In this paper, we solve the local gathering problem of a swarm of n indistinguishable,
point-shaped robots on a two dimensional grid in asymptotically optimal time O(n)
in the fully synchronous FSYNC time model. 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. Compared to the grid, for
gath- ering in the Euclidean plane for the same robot and time model the best
known upper bound is O(n^2).

text: 'We consider the following variant of the two dimensional gathering problem
for swarms of robots: Given a swarm of n indistinguishable, point shaped robots
on a two dimensional grid. 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. '

text: "We consider a scheduling problem where machines need to be rented from the\r\ncloud
in order to process jobs. There are two types of machines available which\r\ncan
be rented for machine-type dependent prices and for arbitrary durations.\r\nHowever,
a machine-type dependent setup time is required before a machine is\r\navailable
for processing. Jobs arrive online over time, have machine-type\r\ndependent sizes
and have individual deadlines. The objective is to rent\r\nmachines and schedule
jobs so as to meet all deadlines while minimizing the\r\nrental cost.\r\n Since
we observe the slack of jobs to have a fundamental influence on the\r\ncompetitiveness,
we study the model when instances are parameterized by their\r\n(minimum) slack.
An instance is called to have a slack of $\\beta$ if, for all\r\njobs, the difference
between the job's release time and the latest point in\r\ntime at which it needs
to be started is at least $\\beta$. While for $\\beta < s$\r\nno finite competitiveness
is possible, our main result is an\r\n$O(\\frac{c}{\\varepsilon} + \\frac{1}{\\varepsilon^3})$-competitive
online\r\nalgorithm for $\\beta = (1+\\varepsilon)s$ with $\\frac{1}{s} \\leq
\\varepsilon\r\n\\leq 1$, where $s$ and $c$ denotes the largest setup time and
the cost ratio of\r\nthe machine-types, respectively. It is complemented by a
lower bound of\r\n$\\Omega(\\frac{c}{\\varepsilon})$."

text: 'We consider online optimization problems in which certain goods have to be
acquired in order to provide a service or infrastructure. 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).'

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.
Our algorithm generalizes a recent result by Limaye et al. who showed that MCVP
with toroidal embedding (genus 1) is in NC when the input contains a toroidal
embedding of the circuit. 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. Similar work
that uses treewidth as parameter was also presented by Elberfeld et al. in [6].'

text: 'Comparative evaluations of peer-to-peer protocols through simulations are
a viable approach to judge the performance and costs of the individual protocols
in large-scale networks. In order to support this work, we present the peer-to-peer
system simulator PeerfactSim.KOM, which we extended over the last years. 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. '

text: Besides the life-as-it-could-be driver of artificial life research there is
also the concept of extending natural life by creating hybrids or mixed societies
that are built from natural and artificial components. In this paper we motivate
and present the research program of the project flora robotica. Our objective
is to develop and to investigate closely linked symbiotic relationships between
robots and natural plants and to explore the potentials of a plant-robot society
able to produce architectural artifacts and living spaces. These robot-plant bio-hybrids
create synergies that allow for new functions of plants and robots. They also
create novel design opportunities for an architecture that fuses the design and
construction phase. 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.

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.

text: Aggregation is a crucial task in swarm robotics to ensure cooperation. We
investigate the task of aggregation on an area specified indirectly by certain
environmental features, here it is a light distribution. We extend the original
BEECLUST algorithm, that implements an aggregation behavior, to an adaptive variant
that automatically adapts to any light conditions. We compare these two control
algorithms in a number of swarm robot experiments with different light conditions.
The improved, adaptive variant is found to be significantly better in the tested
setup.

text: Fitness function design is known to be a critical feature of the evolutionary-robotics
approach. 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.

text: 'Many markets have seen a shift from the idea of buying and moved to leasing
instead. Arguably, the latter has been the major catalyst for their success. Ten
years ago, research realized this shift and initiated the study of "online leasing
problems" by introducing leasing to online optimization problems. Resources required
to provide a service in an "online leasing problem" are no more bought but leased
for different durations. In this paper, we provide an overview of results that
contribute to the understanding of "online resource leasing problems". '

text: 'We consider structural and algorithmic questions related to the Nash dynamics
of weighted congestion games. 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.'

text: In \emph{bandwidth allocation games} (BAGs), the strategy of a player consists
of various demands on different resources. 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.

text: Consider the problem in which n jobs that are classified into k types are
to be scheduled on m identical machines without preemption. A machine requires
a proper setup taking s time units before processing jobs of a given type. The
objective is to minimize the makespan of the resulting schedule. We design and
analyze an approximation algorithm that runs in time polynomial in n,m and k and
computes a solution with an approximation factor that can be made arbitrarily
close to 3/2.
