Monte Carlo methods for simulation of Coulomb collisions in multi-component plasmas

The general DSMC method for solving Boltzmann equation for long-range potentials and Landau-Fokker-Planck equation was proposed by Bobylev and Nanbu in 2000. We present in this paper a completely different approach, which leads to basically the same general method, but makes its essence absolutely clear and transparent. The method is explained for the general case of multi-component plasma. Some rigorous estimates for accuracy of the method are presented.
