摘　　要：为加快果蝇算法的寻优速度和质量;首先将淘汰因子引入果蝇算法(FOA),改进后的果蝇算法较一般果蝇算法能迅速找到最优解;随后将权重和禁忌搜索引入果蝇算法中,使改进后的算法能够动态调整搜索步长,提高搜索的精确度。最后将改进后的果蝇算法(IFOA)应用于管式栈桥的结构优化中,以栈桥结构管的最小质量为目标函数建立优化模型,并与其他学者进行比较,证明改进后的果蝇算法(IFOA)具有更好的性能。The elimination factor is introduced into the fruit fly optimization algorithm(FOA)to accelerate the optimization speed and quality,and the IFOA is faster than the FOA in finding the optimal solution.The weight and taboo search are introduced into the FOA to adjust the search step size and improve the accuracy of the search.IFOA is applied to the structural optimization of the truss,and the optimization model is established with the minimum weight of the truss as the objective function.References prove that the IFOA has better performance.
