Abstract

The water cycle algorithm(WCA) is a simple and effective global optimization algorithm, mainly used for engineering optimization. However, It is easy to fall into the local optimal solution when solving some constrained problems. Therefore, this paper proposes a improved water cycle algorithm based on chaotic Levy distribution. The improved water cycle algorithm was named as CLWCA, and chaos sequence was used as step control parameter based on Levy distribution in combination with the perturbation of Levy distribution and the boundedness of chaotic sequence, in order to enhance the global searching ability of the algorithm. In this paper, CLWCA is applied in the field of engineering model design and compared with the traditional water cycle algorithm(WCA) through experiments. The result verified that the CLWCA algorithm has better global search ability and stability than WCA algorithm in the field of industrial model design.
