非线性权重和柯西变异的蝗虫算法

Grasshopper optimization algorithm with nonlinear weight and cauchy mutation

  • 摘要: 针对蝗虫优化算法收敛速度慢,易陷入局部最优等问题,提出一种基于非线性权重和柯西变异的蝗虫优化算法.首先使用佳点集初始化种群,均匀种群分布.然后将线性权重改进为非线性权重,提高勘探和开发能力.同时对最优个体采用柯西变异,增加跳出局部最优能力.最后通过6个基准函数进行测试,实验表明改进后蝗虫算法收敛速度快、精度高.

     

    Abstract: To overcome the problems of slow convergence, falling into local optima of the standard grasshopper optimization algorithm, a nonlinear weight and cauchy mutation in grasshopperoptimization algorithm is proposed. Firstly, the good point set is applied to initial population and uniform population distribution.Then the linearlyweightis improved to a nonlinear weight toenhance the exploration and exploitation capabilities of thegrasshopper optimization algorithm.At the same time, the cauchy mutation is added to the best grasshopper to increase the ability to jump out of local optima.Finally, six benchmark functions are selected for testing. Experiments show that the improved algorithm has fast convergence and high precision.
