An approximate factorization of multivariate polynomials using improved PSO

In order to avoid the premature convergence of the Particle Swarm Optimization (PSO) algorithm, a modified PSO algorithm is proposed. As an example, the improved algorithm is used for an approximate factorization of multivariate polynomials and the experiment result has proved its efficiency. The method in this paper may be as certain generalization of an precise factorization of multivariate polynomials.
