Use of parallel computation for estimation of coefficients of heat equation by Monte Carlo method

The inverse problem of determination of coefficients of multidimensional heat equation is considered. The method of statistical modeling of trajectories of corresponding systems of stochastic differential equations is applied to the solution of the direct problem and sensitivity analysis. The application of parallel computers allows a significant increase of the...

On existing optimal three-dimensional circulant networks

The optimal circulant graphs have minimum diameter for the given order N and degree ν and, respectively, optimal features with respect to communication delays, reliability and connectivity under implementation as interconnection networks in multimodule supercomputer systems. The questions of existence of optimal (nearly optimal) circulants with the degree ν =...

Numerical experiments with one ILP algorithm

In this paper, a branch and bound algorithm with branching in depth for problems of the integer linear programming (ILP) is considered. The results of solution to large problems of integer and mixed-integer linear programming are presented. A brief information is given on the software for solution to large ILP...
