Abstract
Algorithms related to normalization of autonomous Hamiltonian systems are considered. These include expansion of a Hamiltonian in Taylor ser ies, linear normalization and, finally, nonlinear normalization. Algor ithms most appropriate for use in computer algebra systems from the st andpoint of economy of computer memory are suggested. They are employe d in a program package written in REDUCE.
