A regularity model-based multiobjective estimation of distribution algorithm with reducing redundant cluster operator

► Analyze the drawback of modeling in RM-MEDA. ► Propose a reducing redundant clustering operator (RRCO). ► By combining RRCO with RM-MEDA, propose an improved version of RM-MEDA, named IRM-MEDA. ► Verify the effectiveness of RRCO by many experiments.
