Abstract

Whale optimization algorithm (WOA) is a relatively new population-based metaheuristic optimization method, which has the advantage of fewer control parameters, strong global optimization ability and easy to implement. However, when being used for high-dimensional problems, WOA may be trapped in the local optimum. In this study, we propose an effective whale optimization algorithm called EWOA. Inspired by particle swarm optimization (PSO), a modified position-updated equation by introducing dynamic inertia weight parameter to guide the search of new candidate individuals is presented. In addition, in order to make full use of and balance the exploration and the exploitation of WOA, a nonlinear distance control parameter strategy is proposed. The effectiveness of EWOA is tested based on 26 traditional high-dimensional benchmark problems (D = 30, 100, and 500) and four real-world engineering applications. The experimental and statistical test results demonstrate that EWOA converges to the global optima faster and provides more accurate results than the classical WOA, variants WOA, and other considered population-based metaheuristic algorithms in most cases, especially in solving an optimization problem that has high dimensionality.
