Abstract: A method of multi-PSO with Forbidden Zone（FZPSO） is presented.FZPSO imitates some birds search method，which uses most of the birds search wide range space，and uses a small number of birds search for specific small space to chase the current global best solution to speed up the convergence.By using the concept of the forbidden zone，it is able to change the weakness of the PSO easily fall in the local best solution.Forbidden zone is decided by the size of the forbidden radius，each local optimal solution as the center and the radius of the area designated as forbidden zones.The results show that FZPSO has a strong global convergence capability.
