text: In this paper we present a combined hardware/software approach for synchronizing
the sampling clocks of an acoustic sensor network. A first clock frequency offset
estimate is obtained by a time stamp exchange protocol with a low data rate and
computational requirements. The estimate is then postprocessed by a Kalman filter
which exploits the specific properties of the statistics of the frequency offset
estimation error. In long term experiments the deviation between the sampling
oscillators of two sensor nodes never exceeded half a sample with a wired and
with a wireless link between the nodes. The achieved precision enables the estimation
of time difference of arrival values across different hardware devices without
sharing a common sampling hardware.

text: "In many applications one is faced with the problem that multiple objectives
have to be optimized at the same time. Since typically the solution set of such
multi-objective optimization problems forms a manifold which cannot be computed
analytically, one is in many cases interested in a suitable finite size approximation
of this set. One widely used approach is to find a representative set that maximizes
the dominated hypervolume that is defined by the images in objective space of
these solutions and a given reference point.\r\n\r\nIn this paper, we propose
a new point-wise iterative search procedure, Hypervolume Directed Search (HVDS),
that aims to increase the hypervolume of a given point in an archive for bi-objective
unconstrained optimization problems. We present the HVDS both as a standalone
algorithm and as a local searcher within a specialized evolutionary algorithm.
Numerical results confirm the strength of the novel approach."

text: The averaged Hausdorff distance Δ p is a performance indicator in multi-objective
evolutionary optimization which simultaneously takes into account proximity to
the true Pareto front and uniform spread of solutions. Recently, the multi-objective
evolutionary algorithm Δ p -EMOA was introduced which successfully generates evenly
spaced Pareto front approximations for bi-objective problems by integrating an
external archiving strategy into the SMS-EMOA based on Δ p . In this work a conceptual
generalization of the Δ p -EMOA for higher objective space dimensions is presented
and experimentally compared to state-of-the art EMOA as well as specialized EMOA
variants on three-dimensional optimization problems.

text: Understanding the behaviour of well-known algorithms for classical NP-hard
optimisation problems is still a difficult task. With this paper, we contribute
to this research direction and carry out a feature based comparison of local search
and the well-known Christofides approximation algorithm for the Traveling Salesperson
Problem. We use an evolutionary algorithm approach to construct easy and hard
instances for the Christofides algorithm, where we measure hardness in terms of
approximation ratio. Our results point out important features and lead to hard
and easy instances for this famous algorithm. Furthermore, our cross-comparison
gives new insights on the complementary benefits of the different approaches.

text: In some technical applications like multiobjective online control an evenly
spaced approximation of the Pareto front is desired. Since standard evolutionary
multiobjective optimization (EMO) algorithms have not been designed for that kind
of approximation we propose an archive-based plug-in method that builds an evenly
spaced approximation using averaged Hausdorff measure between archive and reference
front. In case of three objectives this reference font is constructed from a triangulated
approximation of the Pareto front from a previous experiment. The plug-in can
be deployed in online or offline mode for any kind of EMO algorithm.

text: Indicator based evolutionary algorithms have caught the interest of many researchers
for the treatment of multi-objective optimization problems in the recent past
since they deliver the desired approximation of the solution set and due to a
usually better performance compared to dominance based algorithms. Nevertheless,
these methods still suffer the drawback that many function evaluations are required
to obtain a suitable representation of the solution set. The aim of this study
is to present the Directed Search (DS) Method as local searcher within global
indicator based optimization algorithms. For this, we will present the DS in the
context of hypervolume maximization leading to both a new local search algorithm
and a new memetic algorithm. Further, we will present first attempts to adapt
the DS to a class of parameter dependent problems.

text: Here we address the problem of computing finite size Hausdorff approximations
of the Pareto front of four-objective optimization problems by means of evolutionary
computing. Since many applications desire an approximation evenly spread along
the Pareto front and approximations that are good in the Hausdorff sense are typically
evenly spread along the Pareto front we consider three different evolutionary
multi-objective algorithms tailored to that purpose, where two of them are based
on the Part and Selection Algorithm (PSA). Finally, we present some numerical
results indicating the strength of the novel methods.

text: Current StarCraft bots are not very flexible in their strategy choice, most
of them just follow a manually optimized one, usually a rush. We suggest a method
of augmenting existing bots via Fuzzy Control in order to make them react on the
current game situation. According to the available information, the best matching
of a pool of strategies is chosen. While the method is very general and can be
applied easily to many bots, we implement it for the existing BTHAI bot and show
experimentally how the modifications affects its gameplay, and how it is improved
compared to the original version.

text: In multiobjective optimization, the identification of practically relevant
solutions on the Pareto-optimal front is an important research topic. Desirability
functions (DFs) allow the preferences of the decision maker to be specified in
an intuitive way. Recently, it has been shown for continuous optimization problems
that an a priori transformation of the objectives by means of DFs can be used
to focus the search of a hypervolume-based evolutionary algorithm on the desired
part of the front. In many-objective optimization, however, the computational
complexity of the hypervolume can become a crucial part. Thus, an alternative
to this approach will be presented in this paper. The new algorithm operates in
the untransformed objective space, but the desirability index (DI), that is, a
DF-based scalarization, will be used as the second-level selection criterion in
the non-dominated sorting. The diversity and uniform distribution of the resulting
approximation are ensured by the use of an external archive. In the experiments,
different preferences are specified as DFs, and their effects are investigated.
It is shown that trade-off solutions are generated in the desired regions of the
Pareto-optimal front and with a density adaptive to the DI. The efficiency of
the approach with respect to increasing objective space dimension is also analysed
using scalable test functions. The convergence speed is superior to other set-based
and preference-based evolutionary multiobjective algorithms while the approach
is of low computational complexity due to cheap DI evaluations. Copyright © 2013

text: In multi-objective optimization, set-based performance indicators have become
the state of the art for assessing the quality of Pareto front approximations.
As a consequence, they are also more and more used within the design of multi-objective
optimization algorithms. The R2 and the Hypervolume (HV) indicator represent two
popular examples. In order to understand the behavior and the approximations preferred
by these indicators and algorithms, a comprehensive knowledge of the indicator’s
properties is required. Whereas this knowledge is available for the HV, we presented
a first approach in this direction for the R2 indicator just recently. In this
paper, we build upon this knowledge and enhance the considerations with respect
to the integration of preferences into the R2 indicator. More specifically, we
analyze the effect of the reference point, the domain of the weights, and the
distribution of weight vectors on the optimization of $\mu$ solutions with respect
to the R2 indicator. By means of theoretical findings and empirical evidence,
we show the potentials of these three possibilities using the optimal distribution
of $\mu$ solutions for exemplary setups.

text: An indicator-based evolutionary multiobjective optimization algorithm (EMOA)
is introduced which incorporates the contribution to the unary R2-indicator as
the secondary selection criterion. First experiments indicate that the R2-EMOA
accurately approximates the Pareto front of the considered continuous multiobjective
optimization problems. Furthermore, decision makers’ preferences can be included
by adjusting the weight vector distributions of the indicator which results in
a focused search behavior.

text: In this paper we present a system for indoor navigation based on received
signal strength index information of Wireless-LAN access points and relative position
estimates. The relative position information is gathered from inertial smartphone
sensors using a step detection and an orientation estimate. Our map data is hosted
on a server employing a map renderer and a SQL database. The database includes
a complete multilevel office building, within which the user can navigate. During
navigation, the client retrieves the position estimate from the server, together
with the corresponding map tiles to visualize the user's position on the smartphone
display.

text: In this paper we present a modified hidden Markov model (HMM) for the fusion
of received signal strength index (RSSI) information of WiFi access points and
relative position information which is obtained from the inertial sensors of a
smartphone for indoor positioning. Since the states of the HMM represent the potential
user locations, their number determines the quantization error introduced by discretizing
the allowable user positions through the use of the HMM. To reduce this quantization
error we introduce â??pseudoâ?? states, whose emission probability, which models
the RSSI measurements at this location, is synthesized from those of the neighboring
states of which a Gaussian emission probability has been estimated during the
training phase. The experimental results demonstrate the effectiveness of this
approach. By introducing on average two pseudo states per original HMM state the
positioning error could be significantly reduced without increasing the training
effort.

text: Meta-heuristics are frequently used to tackle NP-hard combinatorial optimization
problems. With this paper we contribute to the understanding of the success of
2-opt based local search algorithms for solving the traveling salesperson problem
(TSP). Although 2-opt is widely used in practice, it is hard to understand its
success from a theoretical perspective. We take a statistical approach and examine
the features of TSP instances that make the problem either hard or easy to solve.
As a measure of problem difficulty for 2-opt we use the approximation ratio that
it achieves on a given instance. Our investigations point out important features
that make TSP instances hard or easy to be approximated by 2-opt.
