【摘要】 模拟生物进化过程中导致大量物种灭绝而个别物种幸存的灾变现象,灾变算子在进化操作几十代后除了当前最好解留下来外,重新随机产生其他个体。该文通过分析和实验表明,采用灾变算子可以提高遗传算法小规模群体的多样性,从而避免早熟收敛。更多还原

【Abstract】 Mimicking the cataclysm of the evolution course of eco-systems,in which most species extinct but very few surviving,the cataclysm operator updates all individuals randomly except for the current optimum after tens of generations.This paper demonstrates through analysis and experiment that the cataclysm operator can improve the diversity of the small size populations and avoid the premature convergence in Genetic Algorithm.更多还原
