摘要
通过对遗传算法过早收敛现象的认识,在基于具有性别特征的遗传算法的基础上,提出了染色体表现型遗传的概念。通过染色体表现型遗传,控制变异操作,使变异操作具有确定性,算法的演化过程也能够保持一种连续、稳定的进化状态,从而避免过早收敛。通过函数测试的结果,并与具有性别特征的遗传算法相比,论文算法可以达到更好的全局搜索能力和避免过早收敛的效果。
Understanding the premature phenomenon,the paper introduces a concept that considers chromosome- phenotype as ＂germ plasm＂based on the Genetic Algorithm with sex character.The evolvement process can be kept at a successive and steady evolution state by controlling the mutation regularly.The test of function makes clear that it can reach better ability of searching optimum and better effect of avoiding premature convergence compared with the Genetic Algorithm with sex character.
