the article deals withpseudo-occasional numbers generator value impact on result obtaining in the algorithm of random optimization. Much attention is given to insolvency of the standard pseudorandom number generator Microsoft Office in case of the solution of some random optimization task classes; the authors also offer a variant of solution for revealed problem.
This article is devoted to the study of risks indistinguishability phenomenon from the point of view of probability theory and practical points of view within the scope of congruence theory on algebraic structures. The author considers the deductions corresponding to investigated congruences and their composition. The importance of these residues for improving computing risks performance is shown.
