摘要

Two algorithms for solving systems of linear congruences over residue rings are analyzed. The first algorithm is based on factorizing the modulus and solving the resulting subsystems in the primary rings or fields. The second algorithm introduces certain redundancies during computations. Both algorithms determine the generating vectors of the set of all solutions of the initial system of linear congruences. The article presents the dependences of both algorithms on the modulus size, the number of congruences, and the number of variables in the systems, as obtained in experiments.
