Increasing Successful Offspring and Diversity in Differential Evolution for Engineering Design

We propose a modified version of the differential evolution approach to solve engineering design problems. The aim is to allow each parent in the population to generate more than one offspring at each generation and therefore, to increase its probability of generating a better offspring. To deal with constraints, we use some criteria based on feasibility and a diversity mechanism to maintain infeasible solutions in the population. The approach is tested against penalty function approaches and its performance is also compared against state-of-the-art approaches
