| Abstract: | From view of information entropy,this paper presents a new evolutionary algorithm-adaptive particle swarm optimization algorithm,which is based on the measurements of population diversity.Using the method of applying new measurements of particle swarm diversity,the algorithm uses a special mutation operator,and uses the elite individual reserved strategy,new velocity term and dynamic inertia weight to increase the swarm population diversity.The benchmark tests have showed the power of the algorithm in the n... |
