We describe an algorithm for the generation of relativistic kinematics forcollision and decay processes with multiparticle final states. In the frameworkof this algorithm it is possible to generate different kinematics covering mostof practically interesting cases. One gets a possibility to introduce differentsets of integration variables. As a result different sets of kinematicalsingularities can be regularized. To smooth sharp peaks some regularizationformulas and procedures are used covering most typical cases. The algorithm isrealized in the package CompHEP created for automatic calculations of collisionand decay processes.Comment: 10 pages, standard LaTeX cod
