The research analyzes scientific and methodological approaches for structural parametric identification of fuzzy cognitive models based on time-dependent functional dependencies. In the process constructing identifying models, stages with definition a set concepts unclear relationships over this set, identification, which implements transition to intensity influence between factors, are impleme...

A solution of a nonlinear perturbed unconstrained point-to-point control problem, in which the unperturbed system is differentially flat, considered paper. An admissible open-loop it constructed using covering method. The main part obtained correction limit problem found by expanding series perturbation parameter. first term expansion determined A.N. Tikhonov’s regularization Fredholm integral ...

In this article, the efficiency of time adaptive Rosenbrock and ESDIRK methods is compared for finite volume discretizations for compressible unsteady viscous flows. To make the comparison fair, first an efficient solver for both classes in the JFNK context is identified, where the tolerance TOL that steers time adaptivity is the main input parameter. To specify the tolerances in the sub solver...

Using the game of chess, this paper proposes an approach for the tuning of evaluation function parameters based on evolutionary algorithms. We introduce an iterative method for population member selection and show how the resulting win, loss, or draw information from competition can be used in conjunction with the statistical analysis of the population to develop evaluation function parameter v...
