  • Dynamic norms of random and directed mutations in the genetic algorithm

    Dynamic norms for random and directed mutations in a genetic algorithm for solving the problem of placing elements in an orthonormal lattice have been developed. The principle of these norms is borrowed from the method of imitation annealing. The probability of using random mutations decreases in accordance with the annealing temperature, and the probability of directional mutations increases from iteration to iteration when approaching the optimum.

    Keywords: genetic algorithm, the task of placing the elements, the annealing method, random mutations, directed deterministic mutations

  • Model of an intellectual information system for recognizing users of a social network using bioinspired methods

    Today one of the topical issues is the practical application of the theory of pattern recognition, face recognition, including the definition of a person in the image and its subsequent identification. Such tasks include the extraction of indirect signs of interaction between users of social networks. By identifying the user's face and further searching it in photographs and video files in other profiles, an expansion of the list of basic data available to the analyst is achieved. It is known that the system of computer vision, which is able to recognize faces in a natural and artificial environment under any conditions, has not been implemented to date. One of the obstacles is the variation of the scene - the area where the face is being identified. The article proposes a model of an intelligent information system using bion-spirited methods for preprocessing images in order to expand the range of allowable scene variations.

    "This article describes modeling of uniform system of design and technological preparation and production. The mathematical model is based on base of the theory of probability, the theory of mass service and mathematical statistics. Its basis is markovsky casual process. If the stream of events at the enterprise is stationary, without a consequence and ordinary, this process is called the elementary. The average size of a flow of information of each service is determined by the law of distribution of Erlanga, the stream density is determined by the enterprise, and production transition from a condition to a condition of shops and productions is estimated. When modeling a flow of information on movement of information and details at the enterprise classification of divisions was offered. After the analysis of their activity and a flow of information, details and documents the state graph of uniform system of design and technological preparation and production is constructed. Transitions were thus described and factors are appropriated.
