| 摘 要： | 改进的小生境技术遗传算法因其较好地保持了种群多样性,显示出更优的性能,但它存在操作复杂、比简单遗传算法更费时的缺陷,针对此问题提出一种基于群体间共享的小生境遗传算法.该算法在多模函数的优化中能够保持种群多样性的稳定性,获取合适的子种群规模,从而以更快的收敛速度获得更优的解.研究结果表明,该算法不但可以有效地克服标准遗传...

| Abstract: | The improved Genetic Algorithm based on Niche technique shows a better performance because it keeps the population diversity well,but it is more complex than SGA in operation and is more time-consuming.This paper presents a new method based on populations-sharing.It can keep the population diversity stable and determine a suitable size of sub population in optimization of multimodal functions,so it can obtain more optimal solutions at a much higher speed.The research results show that new algorithm can not ... |
