Finding the Maximum Module of the Roots of a Polynomial by Particle Swarm Optimization

Alter the theorem which is used to determine whether all roots of a polynomial are in unit click is given, and two particle swarm optimizations for finding the maximum module of the roots of a polynomial based on the theorem are proposed Finally, several computer simulation results show that using these algorithms to find the maximum module of roots of a polynomial are more efficient and feasible, the convergent speed is much faster and the accuracy of results is much higher
