    Pre-decomposition of discrete optimization problems to speed up the branch and bound method in a distributed computing environment
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 719-725

    The paper presents an implementation of branch and bound algorithm employing coarse grained parallelism. The system is based on CBC (COIN-OR branch and cut) open-source MIP solver and inter-process communication capabilities of Erlang. Numerical results show noticeable speedup in comparison to single-threaded CBC instance.

    Non-uniform cellular genetic algorithms
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 775-780

    In this paper, we introduce the concept of non-uniform cellular genetic algorithm, in which a number of parameters that affect the operation of genetic operators is dependent on the location of the cells of a given cellular space. The results of numerical comparison of non-uniform cellular genetic algorithms with the standard genetic algorithms, showing the advantages of the proposed approach while minimizing multimodal functions with a large number of local extrema, are presented. The coarse-grained parallel implementation of the non-uniform algorithms using the technology of MPI is considered.
