摘要
针对经典麻雀算法种群多样性逐渐减少和求解稳定性不强的缺点,本文对其提出了一种改进方法.该方法通过引入Sine混沌映射初始化麻雀种群(Sine-SSA),达到了增加初始麻雀种群多样性的目的.本文同时对多种混沌映射的改进效果进行了对比,文中共采用了8个基准函数的多重维度,不同测试函数的仿真效果表明了采用Sine混沌映射改进的麻雀算法相较于其他映射的收敛速度与寻优精度都为最优,也证实了该方法在增加麻雀种群多样性上的稳定性.
Abstract
In view of the shortcomings of the classical sparrow algorithm,namely the gradual reduction of population diversity and the weak solution stability,an improved method is proposed in this paper.By introducing the Sine chaotic map to initialize the sparrow population(Sine-SSA),the purpose of increasing diversity of the initial sparrow population is achieved.At the same time,the improvement effects of various chaotic mappings are compared.In this paper,the multiple dimensions of eight benchmark functions are adopted.The simulation results of different test functions show that the convergence rate and optimization accuracy of the improved sparrow algorithm using Sine chaotic mapping are optimal compared with those of other mappings,which also confirms the stability of this method in increasing the diversity of sparrow population.
