摘要: 将遗传算法(GA)中进化算子的作用,抽象成从一个离散拓扑空间到另一个离散拓 扑空间的映射,将遗传算法等价为离散拓扑空间上的转移自映射的一个复合函数.以符号动 力系统(CS)为工具,证明了满足一定条件的有限群体的遗传算法(周期性现象的存在),构成 Devaney意义下的混沌;给出了基于二进制编码的有限群体遗传算法在Bowen意义下的拓扑 熵的范围.Abstract: The evolutionary operators are considered as a mapping from one discrete topological space into another one, and GAs are equivalent to a composite function of shift map. Dynamical systems are applied as a tool to do it. The paper demonstrates that the GAs with finite population are chaotic in devaney. Hence, the scope of topological entropy in bowen is presented.
