Evaluating differential evolution with penalty function to solve constrained engineering problems

Abstract

Over the the years, several metaheuristics have been developed to solve hard constrained and unconstrained optimization problems. in general, a metaheuristic is proposed and following researches are made to improve the original algorithm. in this paper, we evaluate a not so new metaheuristic called differential evolution (DE) to solve constrained engineering design problems and compare the results with some recent metaheuristics. Results show that the classical de with a very simple penalty function to handle constraints is still very competitive in the tested problems. (C) 2012 Elsevier B.V. All rights reserved.
