New hybrid particle swarm optimization

By introducing chaotic search and mutation mechanism,population can overcome the shortcomings of stagnation and trapping into local optimums.When the population is stagnation,chaotic search is used to find a better point firstly.If this point does not meet the precision of mutation,then mutation mechanism will make effort.Chaotic search can continuously optimize when the population is stagnation,mutation mechanism helps the population break away from local optimum when it has trapped into the local optimum.Experimental results show that the new algorithm is relatively obvious for the ability of global optimization.
