【摘要】 本文针对进化策略在解决比较复杂问题时出现收敛速度缓慢这一问题的原因进行分析,提出将原来变异算子中的用高斯随机变量产生的随机扰动量改用柯西随机变量产生的随机扰动量来代替的一种新的变异方法.通过对几个标准函数进行模拟进化,说明该方法是合理、有效的.更多还原

【Abstract】 Based on the reason of the slow convergence for the complicate problem using evolutionary Strategies, this paper presents a new mutation method which uses a Cauchy mutation operator instead of Gaussian mutation operator as a primary search operator. It is shown that this method is reasonable and feasible through simulating evolution by several remark functions.更多还原
