The article provides a problem statement and its description. There are the basic parameters for the description. To solve the problem of the proposed genetic algorithm with modified genetic operators. A description of the algorithm, a description of all changes in the operators, as well as testing for test problems of Solomon. The results are compared with the best global results

12. Specifications as ontologies [№4 за 2009 год]
Authors: Манцивода А.В., Стукушин Н.О.

In this paper we consider an approach to formalization of specifications based on the Semantic Web methods and ontologies. First, ontologies are good for the description of the formal and strict semantics of specifications. Second, specification constructs represented as components of ontologies can be directly used in relevant implementations, making these implementations also part of the SW.

13. The imiia system and its usage for building multi-agent systems [№4 за 2009 год]

The paper describes the experience of usage of the system of imitational modeling for interaction in intelligent agents (IMIIA). The main objective of the IMIIA design is to check the applicability of the proposed models, methods and algorithms for intelligent agents interaction and their architectures in the development of MAS prototypes for various problem areas. Examples of implemented MAS prototypes for several applications have been provided.

14. Safety of system of information-analytical support of researches [№4 за 2009 год]
Authors: Чернова Е.В., Попова Е.В., Попова И.В., Зленко И.В.

In article the main threats of an intelligence system of support of researches of high school are considered, requirements of a policy of informational safety of the system are resulted, allowing to lower probability of implementation of the revealed threats.

15. Topology and resistance of local-world networks [№4 за 2009 год]
Authors: Гаджиев Б.Р., Гибина Е.Ю., Прогулова Т.Б., Щетинина Д.П.
Visitors: 10870
The topology and the resistance of local-world networks are investigated. Different strategies of the local-world forming are analyzed. The degree distribution and the correlation type in considered networks are defined. The resistance of local-world networks to random failures and targeted attacks is considered. Keywords: complex networks, scale-free networks, local-world networks, degree distribution, correlated networks, random failures, targeted attacks, resistance of networks.

16. Informational system of gis database interaction [№4 за 2009 год]
Author: Чернецова Е.А.

An informational System of GIS database interaction is proposed. It represents web-application and allows to access satellite monitoring information for many users which can analyze images and store their analysis results for effective and quick object detection. The proposed informational System has a program realization.

17. Architecture of the integrated system of designing situational agent modelling [№4 за 2009 год]
Authors: Суконщиков А.А., Суконщиков К.А.

In article questions of construction of the integrated system of designing situational agent modelling are considered. Models of agents allow to carry out research of various situations which arise in complex dynamic system. All models of agents are executed on the basis of the uniform mathematical device – integrated attribute networks Petri which include such expansions as the indistinct networks Petri, predicate-transitive networks, the neural networks Petri.

18. An analytical performance model for distributed computing systems [№4 за 2009 год]
Authors: A.P. Afanasiev, Посыпкин М.А., Хританков А.С.

Parallel computing allows for solving large problems much faster and the efficiency metrics are defined and well-known. There are no such metrics or performance models for distributed systems that are becoming more widely spread. In this paper, we address the problem of defining what does it mean a distributed system is efficient or has high performance? We propose a natural extension of a classical analytical performance model to distributed systems.

19. Packet networks characteristics research with using nodal method of tensor analysis [№4 за 2009 год]
Author: Пономарев Д.Ю.
Visitors: 11757
There is presents results of program system engineering for packet networks probability-time characteristics estimation with using “nodal” method of tensor analysis. Developed program compute network nodes utilization with tensor method for the purpose of using derived results for determination of systems parameters: queue lengths, systems delay time, overflow and stationary probabilities for every of systems.

20. Scalar function algorithm minimization of many variables with interval limitation on variables [№4 за 2009 год]
Authors: Бояринов Ю.Г., Dli M.I.
Visitors: 10418
The article deals with the search scalar function algorithm minimization of many variables with implicit function and interval limitation on variables. The main idea of algorithm, that the least value the function takes at one of the hypeparallelepiped apexes – the area of possible values argument, is in successive bypass of apexes from the initial point to the function decrease. The program algorithm realization is suggested in the MATLAB sphere.
