- Abstract:
-
To maintain population diversity and find a sufficient number of equivalent solutions in multimodal multi-objective optimization, a multimodal multi-objective particle swarm optimization algorithm with zoning and local searches (ZLS-SMPSO-MM) is proposed in this study. In the proposed algorithm, which is based on zoning search and local search, the entire search space is divided into several subspaces to maintain population diversity and reduce search difficulty. Subsequently, an existing self-organizing multimodal multi-objective particle swarm algorithm is used to search equivalent solutions and mine neighborhood information in each subspace, and the covariance matrix adaptation algorithm, which has a better local search ability, is utilized for a refined search in promising regions. Lastly, the performance of ZLS-SMPSO-MM is tested on 14 multimodal multi-objective optimization problems and compared with that of other five state-of-the-art algorithms. Experimental results show that the proposed algorithm can find more equivalent solutions in the decision space and its overall performance is better than that of the compared algorithms.
