摘要
进化计算存在的遗传漂移现象使种群均匀地收敛于单一的优良解,导致早熟收敛或可选优良解的丢失,小生态技术是一种形成和维持稳定子种群、抑制遗传漂移的并行进化技术。系统地综述了小生态技术研究的主要成果,归纳了存在的问题,指出了进一步的研究方向。
Genetic drift in evolutionary computation drives the population converging on a highly fit solution quickly and uniformly, and causing premature convergence or lost of global optimum and alternative local optima. Niching technique is a class of parallel evolution method that suppresses genetic drift by forming and maintaining stable subpopulations. The major research results are reviewed in current niching evolutionary algorithms. The existing problems are summarized. The future research directions are proposed.
