Abstract

A class of algorithms for the numerical treatment of the Boltzmann equation is introduced. The basic idea is a more general procedure of modelling collisions between particles. This procedure is based on a random weight transfer from the particles with the pre-collision velocities to the particles with the post-collision velocities.
