一种改进的遗传算法

小生境遗传算法已在多峰值函数求解中得到了广泛应用．本文针对隔离小生境遗传算法进行了研究，并对其进行相应的改进，提出了小生境群体中小生境对的概念。通过小生境对，小生境群体间的联系得到加强，理论分析与实验结果表明：改进后的算法，收敛速度和效率整体上得到了的提高。

The niche genetic algorithm has been used in the muhimodal functions. In the paper, the isolated niche genetic algorithm is investigated and is ameliorated in some aspects. The conception of the couple niche group is put forward firstly, by which the relation between the niche groups is enhanced. The analysis of the theories and the result of researches show that the convergent velocity and efficient of the improved algorithm are wholly strengthened.
