text: The steady supply of new optimization methods makes the algorithm selection
problem (ASP) an increasingly pressing and challenging task, specially for real-world
black-box optimization problems. The introduced approach considers the ASP as
a cost-sensitive classification task which is based on Exploratory Landscape Analysis.
Low-level features gathered by systematic sampling of the function on the feasible
set are used to predict a well-performing algorithm out of a given portfolio.
Example-specific label costs are defined by the expected runtime of each candidate
algorithm. We use one-sided support vector regression to solve this learning problem.
The approach is illustrated by means of the optimization problems and algorithms
of the BBOB’09/10 workshop.

text: Exploratory Landscape Analysis subsumes a number of techniques employed to
obtain knowledge about the properties of an unknown optimization problem, especially
insofar as these properties are important for the performance of optimization
algorithms. Where in a first attempt, one could rely on high-level features designed
by experts, we approach the problem from a different angle here, namely by using
relatively cheap low-level computer generated features. Interestingly, very few
features are needed to separate the BBOB problem groups and also for relating
a problem to high-level, expert designed features, paving the way for automatic
algorithm selection.

text: A large proportion of plastics today is compounded, which means the process
from refining a raw material to the processable material. For this process compounding
extruders are used which mostly involve tightly intermeshing, co-rotating twin
screw extruders. These extruders consist of two closely spaced screws which rotate
in the same direction and convey the raw material to the screw tip. These screws
are surrounded by several barrel modules which heat or cool the material. As the
whole design of the machine is modularly arranged the process behavior of a twin
screw extruder depends for the main part on the arrangement of the screw and the
barrel elements. Until today this arrangement and process optimization is conducted
by experienced engineers and with the help of trial-and-error methods. Furthermore,
theoretical models are used with which the behavior of the extruder is estimated.
As these models are mostly very complex they are only made available with the
realization in different software projects. One of the tools is called SIGMA.
Within this paper SIGMA is introduced as a software to optimize a twin screw extruder.
SIGMA supports the engineer already in the early stages of the extruder arrangement.

text: In double-sided markets for computing resources an optimal allocation schedule
among job offers and requests subject to relevant capacity constraints can be
determined. With increasing storage demands and emerging storage services the
question how to schedule storage jobs becomes more and more interesting. Since
such scheduling problems are often in the class NP-complete an exact computation
is not feasible in practice. On the other hand an approximation to the optimal
solution can easily be found by means of using heuristics. The problem with this
attempt is that the suggested solution may not be exactly optimal and is thus
less satisfying. Considering the two above mentioned solution approaches one can
clearly find a trade-off between the optimality of the solution and the efficiency
to get to a solution at all. This work proposes to apply and combine heuristics
in optimization to gain from both of their benefits while reducing the problematic
aspects. Following this method it is assumed to get closer to the optimal solution
in a shorter time compared to a full optimization.

text: New mechatronic systems, called self-optimizing systems, are able to adapt
their behavior according to environmental, user and system specific influences.
Self-optimizing systems are complex and due to their non-deterministic behavior
comprise hidden risks, which cannot be foreseen in the design phase of the system.
Therefore, this paper presents modifications of the current condition monitoring
policy, to be able to cope with this new kind of systems. Beside avoiding critical
situations evoked by self-optimization, the proposed concept uses self-optimization
to increase the dependability of the system. In this case, the concept is applied
to the active guidance module of an innovative rail-bound vehicle.

text: Three cis-dioxovanadium(V) complexes with similar N -salicylidenehydrazide
ligands modeling hydrogen bonding interactions of vanadate relevant for vanadium
haloperoxidases are studied by 51V solid-state NMR spectroscopy. Their parameters
describing the quadrupolar and chemical shift anisotropy interactions (quadrupolar
coupling constant C Q , asymmetry of the quadrupolar tensor η Q , isotropic chemical
shift δ iso , chemical shift anisotropy δ σ , asymmetry of the chemical shift
tensor η σ and the Euler angles α , β and γ ) are determined both experimentally
and theoretically using DFT methods. A comparative study of different methods
to determine the NMR parameters by numerical simulation of the spectra is presented.
Detailed theoretical investigations on the DFT level using various basis sets
and structural models show that by useful choice of the methodology, the calculated
parameters agree to the experimental ones in a very good manner.

text: 'In this paper, we present a framework that supports experimenting with evolutionary
hardware design. We describe the framework''s modules for composing evolutionary
optimizers and for setting up, controlling, and analyzing experiments. Two case
studies demonstrate the usefulness of the framework: evolution of hash functions
and evolution based on pre-engineered circuits.'

text: For human-machine interfaces in distant-talking environments multichannel
signal processing is often employed to obtain an enhanced signal for subsequent
processing. In this paper we propose a novel adaptation algorithm for a filter-and-sum
beamformer to adjust the coefficients of FIR filters to changing acoustic room
impulses, e.g. due to speaker movement. A deterministic and a stochastic gradient
ascent algorithm are derived from a constrained optimization problem, which iteratively
estimates the eigenvector corresponding to the largest eigenvalue of the cross
power spectral density of the microphone signals. The method does not require
an explicit estimation of the speaker location. The experimental results show
fast adaptation and excellent robustness of the proposed algorithm.
