The paper proposes a simple mutual transformation mechanism for divergent and nondivergent difference forms of transfer operator, allowing to present a known DSn method as four-parametrical family of difference schemes and analyze some algorithm for selecting scheme parameters. Numerical calculations on large grids have corroborated high efficiency of this algorithm.
