Study on a New MOPSO and Its Applications

To update the performance of the multi-objective optimization method,a new MOPSO(multi-objective particle swarm optimization) algorithm is proposed on the basis of earlier works relevant to particle swarm optimization and in combination with the optimization of a specific copper electrolysis process.Introducing the size-variable external data set and fast sorting to reduce the time for computation,both the congestion operator and strong predominance are used in the algorithm to provide a good diversity in i...
