| 摘 要： | 蝙蝠算法是一种新兴的元启发式算法，基本蝙蝠算法（BA）存在寻优精度低、易陷入局部最优等缺点。将椋鸟群的集体性行为引入到基本蝙蝠算法中，有效地提高了算法的搜索范围；引入线性递减权重，用于平衡全局搜索和局部搜索。通过一些测试函数对该算法进行仿真研究，结果表明改进的蝙蝠算法有效地避免了种群个体陷入局部最优，提高了算法的寻优精度，优化效果得到改善。

| Abstract: | Bat algorithm (BA) is a new metaheuristic algorithm.However,the standard BA has some shortcomings,e.g.,low convergence precision and easily relapsing into the local optima.In this work,by introducing the collective behavior of the starling group into BA algorithm,the searching range of the standard BA algorithm can be effectively improved.Besides,a linear decreasing weight is introduced to balance the global search and the local search.Simulation results from Benchmark functions show that the improved algorithm can effectively avoid the local optimum and attain higher convergence precision. |
