These two algorithms are used to construct chaotic attractors of p112- and p1a1-equivariant mappings of frieze groups, and an improved eugenic genetic algorithm is presented for avoiding "genetic drift" phenomenon from the eugenic genetic algorithm.

本文将蒙特卡罗搜索法与优生遗传算法应用于构造饰带群等价映射模型p112与模型p1a1混沌吸引子,并针对“遗传漂移”现象提出了改进的优生遗传算法。
