摘　　要：标准烟花算法粒子间交流机制存在缺陷,且对最优点位置不在原点和原点附近时的目标函数求解能力差,对此提出差分进化引导趋化算子的烟花算法(BFA)。利用差分进化算法和趋化算子的局部搜索优势,在每一次迭代的过程中不断寻找这一代的最好个体,通过最优个体信息对局部粒子维度信息进行修改从而使得整个群体得到改善,8个标准和增加位置偏移的测试函数仿真结果表明,BFW相比于原始烟花算法(FA),粒子群算法和SPSO在寻优精度和寻优速度上有了较好的提高。In order to solve the default of the fireworks algorithm inter-particle exchange mechanism and the disadvantage that the optimal position is not solved by the objective function near the origin and the origin come up with fireworks algorithm optimization with chemotaxis operator(BFW).Using the local search advantage of the chemotaxis operator to find the best individual in every iteration to improve the whole population's search ability.The improved algorithm has been tested on 8 benchmark functions.The experimental results show that BFW has better behaviors in convergence accuracy and speed.
