一种使用长定义距模式的遗传算法
首发时间:2007-03-29
摘要:基本遗传算法(SGA) 和模式定理都是基于二进制编码,关于选择、交叉和变异算子的,但是交叉算子对模式的破坏性很大,尤其对定义距较长的模式,而且关于交叉算子的重组功能模式定理却没有给出清晰的解释。设计了针对长定义距模式的再生算子,并提出采用再生算子代替交叉算子的长模式遗传算法,仿真结果表明了再生算子的有效性。

Design of Genetic Algorithms using Long Defining Length Schema
Abstract: Simple Genetic Algorithms and Schema Theorem are both based on binary encoding using selection , crossover and mutation operator, but crossover operator can be destructive to schema , especially to longer defining schema, moreover schema theorem have not clear explanation about recombination function of crossover operator. Reproduce operator with the aim of using long defining length schema is designed and Long Schema Genetic Algorithms replaced crossover with reproduce operator is put forward. Experimental results proved the validity of reproduce operator.
