Abstract
In this paper we deal with the problem of extremal parameter grouping. The problem formulation, the algorithms of parameter grouping and the fields of implementation are presented. The deterministic algorithms of extremal parameter grouping often find the local maximum of the functional, characterizing the quality of a partition. The problem has been formulated as a problem of combinatorial optimization and attempted to be solved using the simulated annealing strategy. The algorithms, realizing such a strategy and devoted to the solving of the problem concerned, are proposed and investigated.

Abstract
This paper is devoted to the application of adaptable difference schemes for the simulation of propagation and interaction of focused laser beams. New effective processes for the solution of stationary nonlinear optics problems are proposed. Simulation results on real experiment data show the advantages of such schemes and iteration processes.

Abstract
A fault-tolerant software unit is composed of N≥2 diverse member units, usually developed by N separate teams, and an execution environment. The development process employs diversity requirements, communication protocols, and inter-team isolation rules to promote the greatest possible independence of team efforts and diversity among their products. The principal models, specification, building, evaluation, and system integration of fault-tolerant software are discussed, and goals for future work are suggested.
