Coevolutionary algorithm is a self-tuned optimization procedure based on genetic algorithms. Algorithm adaptation for constrained and multiobjective optimization problems and its efficiency investigation are considered. It is demonstrated that coevolutionary algorithm is not less effective than best for problem-in-hand individual conventional algorithm for constrained one-objective optimization problems and coevolutionary algorithm is as effective as average individual algorithm for multiobjective optimization problems.

We introduce the original software tools for building and analysis of the stratified system of structural complexity and similarity models. The models are based on the characterization of placement of fragments in a system topology. The software tools are implemented as a subsystem of the integrated research environment «Graph Model Workshop» and are used in studies of equality and tolerance relations of various graph models of systems.

26. Building and optimizing production program of separation plant [№4 за 2010 год]

The article describes the problem of creating production program of separation plant. It presents the algorithm for building the separation plant production program to satisfy the requirements taking into account the available resources and algorithm for optimization of the built program using improved method of Zoytendeik.

27. Software package for building genomic profiles for weight matrices [№4 за 2010 год]
Author: Cheremushkin E.S.

Aim of this work was to develop software package for analysis of genomic profiles of positional weight matrices. By genomic profile author means a histogram, that is build for density of binding sites distribution found with this matrix. Software allows to build genomic profiles for different matrices and search cutoffs. It was found experimentally that matrix profile is independent on given cutoffs.

28. Fuzzy set approach to classifier combination [№4 за 2010 год]
Authors: Багрова И.А., Пономарев С.А., Сорокин С.В., Сытник Д.А.
Visitors: 14321
Fuzzy set approach for combining of multiple classifiers is introduced. Proposed algorithms are evaluated on the optical character recognition task. Advices on usage of considered algorithms are given.

29. Prediction based on the allocation of border implementations of dynamic systems [№4 за 2010 год]
Authors: I.G. Sidorkina , Егошин А.В., Шумков Д.С.

The paper proposes two methods for predicting complex signal based on multilayer perceptron and SVM. The length of training set for the predictor is based on the allocation of border implementations of dynamic systems in the signal, in order to use for learning the last fragment of the signal with the quasi-stable dynamic. This change-point is found in the local fractal dimension of the signal. The presented methods were developed in software package.

30. H.264 video coding standard [№4 за 2010 год]
Authors: Куликов Д.Л., Стрельников К.Н.
Visitors: 12552
Novel video coding artifacts concealment method is proposed in this paper. Main idea for deblocking is to use basic deblocking algorithms and reconstruct grain that present in many video sequences captured by professional analog cameras. Proposed method makes it possible to decrease blocking artifacts perceptibility and to mask imperfections for deblocking algorithms results. Proposed algorithm result analysis was performed with the help of SAMVIQ methodology for subjective video quality assessments.
