基于克隆选择原理的自适应免疫性遗传算法研究

针对遗传算法中存在着收敛方向无法控制和没有记忆能力等缺陷,提出了具有免疫功能的克隆遗传算法.该算法把目标函数和制约条件作为抗原,保证所生成的抗体与问题直接相关联,使收敛方向得以控制;对抗原亲和力高的抗体进行克隆记忆,促使优良个体的发育成熟并能有效地遗传到下一代;同时,基于浓度的概念提出对抗体数量进行抑制,确保群体更新的多样性,避免早熟.通过理论分析和实验研究,证明该算法具有快的收敛速度和搜索能力,是一种有效的生物计算方法.

Research on adaptive immune genetic algorithms based on clone selection principles

In view of the defects that there is no way to control convergence orientation and also no memory capability in genetic algorithms(GA), a clone genetic algorithm is proposed which can make genetic algorithm possess immune function.In this algorithm, aim function and restriction condition are served as antigens(Ags) so as to ensure the created antibodies(Abs) directly related to the problem-solving, thus, convergence orientation in GA is controlled ultimately, the antibodies with high affinities are cloned a...
