一种改进的进化策略研究

Study on Improved Evolutionary Strategy

提出了一种新的进化策略,基于物种保护的混合变异算子进化策略,它混合了四种不同的变异算子(Gaussian、Cauchy、Levy和单点(Single Point)),并结合了使局部优化不被陷入困境的物种保护技术.使用国际通用标准函数来测试这种新算法,仿真的结果表明了基于物种保护的混合变异算子进化策略优于任何一种纯策略的进化策略.

In this paper,an example of such strategies is introduced which employs four different mutation strategies:Gaussian,Cauchy,Levy,single-point.It also combines with the technique of species conservation to prevent the evolutionary strategy from being trapped in local optima.This mixed strategy has been tested on benchmark functions.The simulation results show that the mixed mutation strategy is superior to any pure mutation strategy.
