Abstract:Particle Swarm Optimization(PSO) algorithm converges more slowly as the dimension increases, which easily cause the local optimum. A Cooperative Particle Swarm Optimization(CPSO) algorithm is presented, by using the way of cooperation to improve the premature convergence problem of standard algorithm. CPSO, Cooperative Coevolutionary Genetic Algorithm(CCGA), Genetic Algorithm(GA), PSO algorithm are compared with the test of standard function. The results indicate that CPSO algorithm shows better performance in a number of benchmark optimization problems, compared with the traditional algorithm.
