Abstract: A multi-objective optimization based on suitable-distribution particle swarm (SDPS) is discussed. There are simple rules and quick convergence speed for SDPS. Also, it can ensure the final solutions more dispersive and symmetrical. A new method is proposed to update the external memory and fix the fit-sharing radius. In order to compare with other algorithms, the proposed algorithm is used to solve some well-known multi-objective functions. It is proved that the proposed algorithm is able to find the solutions which are much more exact and efficient convergence to the true Pareto front and much more well-proportioned distribution over the Pareto front.

Key words: suitable-distribution, particle swarm, multi-objective optimization, Pareto front
