Abstract

The recombination operator plays a very important role in genetic algorithms. We present binary coded genetic algorithms in which more than two parents are involved in the recombination operation. We propose two types of multi-parent recombination operators, the multi-cut (MX) and seed crossover (SX). Each of these operators is a natural generalization of two parents recombination operator. These operators are evaluated on the De Jong standard test functions. The results showed clearly that the multi-parent recombinations lead to better performance, although the performance improvement for different techniques were found to be dependent on problems.
多亲本重组对二进制编码遗传算法的影响
重组算子在遗传算法中起着非常重要的作用。我们提出了二进制编码遗传算法,其中两个以上的父母参与重组操作。我们提出了两种类型的多亲本重组算子:多切算子(MX)和种子交叉算子(SX)。这些算子中的每一个都是两个父重组算子的自然推广。这些操作符在德容标准测试函数上进行了评估。结果清楚地表明,多亲本重组导致更好的性能,尽管不同技术的性能提高被发现是依赖于问题。
