Abstract: In original MCPSO，there is no information sharing among slave swarms except that the information of the best performing particle is broadcasted to the master swarm.To deal with this issue an improved MCPSO with Center Communication（MCPSO-CC） is proposed，where a center communication strategy is used to transfer the information among all the sub-swarms and accelerate the convergence.Experimental results show that MCPSO-CC achieves not only better solutions but also faster convergence.
