The covariancematrix adaptation evolution strategy (CMA-ES) is one of themost powerful evolutionary algorithms for real-valued single-objective optimization. In this paper, we develop a variant the CMA-ES multi-objective optimization (MOO). We first introduce single-objective, elitist using plus-selection and step size control based on success rule. This algorithm compared to standard CMA-ES. turns out be slightly faster unimodal functions, but more prone getting stuck in sub-optimal local...
