摘要
针对基本鲸鱼优化算法寻优精度低、收敛速度慢及容易陷入局部最优等缺陷,提出了一种动态搜索和协同进化的鲸鱼优化算法。首先,通过等价替换和Faure序列提高初始解的质量;其次,通过对种群进行分工,提高种群多样性并增强算法跳出局部最优解的能力;最后,根据种群进化信息动态调整搜索策略,从而提高算法的收敛速度和寻优精度。仿真实验结果表明,提出的改进算法相比基本鲸鱼优化算法和部分改进算法具有较好的寻优性能。
Aiming at the shortages of the basic whale optimization algorithm with low optimization precision,slow convergence speed and easy to fall into local optimum,this paper proposed a new algorithm based on dynamic search and cooperative learning. Firstly,it used equivalent replacement and Faure sequences to enhance the quality of initial solution. Secondly,it improved the population diversity and enhanced the ability to jump out of local optimal solutions through the division of population. Finally,in order to improve the convergence rate and precision,it dynamically adjusted the search strategy of the algorithms according to the population evolutionary information. The experimental results show that the proposed algorithm is much better than basic whale optimization algorithm and its several improved algorithms in optimization performance.
