报告摘要：

WOA is a newly developed meta-heuristic algorithm which performs well in solving optimization problems. We added two strategies to the original WOA algorithm. The first is to use chaos mechanism to generate initial value to improve the convergence speed of the algorithm. The second is to use the opposition-based learning method to balance the exploration and development ability of the algorithm to help the algorithm jump out of local optimal solutions. The proposed algorithm is compared with other algorithms on unimodal functions, multimodal functions and fixed dimensional multimodal functions, and it is applied to a famous engineering design problem. The results show that the combination of the two strategies can improve the convergence speed and enhance the global search ability of the original WOA algorithm. The OBCWOA algorithm proposed in this paper is a potential algorithm with better performance than other existing algorithms.
