Cooperative evolutionary particle swarm optimization algorithm with multi-populations

A new particle swarm optimizer(PSO),called the cooperative evolutionary PSO with multi-populations,is presented based on the analysis of the standard PSO.The whole group is divided into several sub-groups.Every subgroup evolved independently and updated sharing information periodically.Two different updating strategies are adopted and the two methods are analyzed in detail.The experimental results show that the properly communication period can greatly improve the convergence.
