The problem-solving time and the solution accuracy are expressed as functions of a parameter. An optimization problem of choosing the parameter using a "time cost---solution accuracy" criterion is considered. A Pareto-optimal set of solutions is obta

We propose a modification of the additive splitting algorithm to solve the convection-diffusion problem using an efficient finite-difference scheme. The modification decreases the number of data exchanges and their amount during the numerical solutio
