Abstract
We describe an algorithm of multi-particle phase space integration for collision and decay processes realized in CompHEP package version 3.2 . In the framework of this algorithm it is possible to regularize an a rbitrary set of singularities caused by virtual particle propagators. The algorithm is based on the method of the recursive representation o f kinematics and on the multichannel Monte Carlo approach.
