Abstract

Many problems occurring in engineering can be formulated as min-max optimization problems, for instance, in game theory, robust optimal control and many others. Min-max problems are considered difficult to solve, specially constrained min-max optimization problems. Approaches using co-evolutionary algorithms have successfully been used to solve min-max optimization problems without constraints. We propose a novel differential evolution approach consisting of three populations with a scheme of copying individuals for solving constrained min-max problems. Promising results have been obtained showing the suitability of the approach.
