Differential Evolution (DE) is a highly competitive numerical optimization method for constrained optimization problems. In this study, a new selective pressure technique is applied in DE, which considers both function values and constraint violations with respect to ϵ-constraint level. The new modification was tested against known variants of constrained DE, and it is shown that selective pressure allows significant improvement of algorithm performance in various application scenarios.
