    Solution of optimization problem of wood fuel facility location by the thermal energy cost criterion
    Computer Research and Modeling, 2012, v. 4, no. 3, pp. 651-659

    The paper contains a mathematical model for the optimal location of enterprises producing fuel from renewable wood waste for the regional distributed heating supply system. Optimization is based on total cost minimization of the end product – the thermal energy from wood fuel. A method for solving the problem is based on genetic algorithm. The paper also shows the practical results of the model by example of Udmurt Republic.

    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.

    Keywords: branch and bound algorithm, coarse grained parallelism.

    An implementation of a parallel global minimum search algorithm with an application to the ReaxFF molecular dynamic force field parameters optimization
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 745-752

    Molecular dynamic methods that use ReaxFF force field allow one to obtain sufficiently good results in simulating large multicomponent chemically reactive systems. Here is represented an algorithm of searching optimal parameters of molecular-dynamic force field ReaxFF for arbitrary chemical systems and its implementation. The method is based on the multidimensional technique of global minimum search suggested by R.G. Strongin. It has good scalability useful for running on distributed parallel computers.

    Keywords: numerical simulation, molecular dynamics, reactive force field, chemically reactive systems, parameter optimization, parallel algorithm, absolute extremum search.
