遗传算法中控制种群多样性的自适应机制

Self-Adaptation Mechanism to Control the Diversity of the Population in Genetic Algorithm

Chaiwat Jassadapakorn, Prabhas Chongstitvatana

摘要:

应用遗传算法的问题之一是存在进化过程收敛过快导致陷入局部最优解的情况。为了克服这个问题,必须确定候选解的适当多样性。大多数现有的多样性维护机制需要一个问题的具体知识,正确设置参数。本文提出了一种无需明确参数设置就能控制种群多样性的方法。提出了一种基于交配偏好特征竞争的自适应机制。它可以使种群适应问题的适当多样性。基于九个著名的测试问题进行了实验,以衡量所提出的方法的有效性。在最佳参数设置下,自适应方法的性能与传统的遗传算法相当。

英文摘要:

One of the problems in applying Genetic Algorithm is that there is some situation where the evolutionary process converges too fast to a solution which causes it to be trapped in local optima. To overcome this problem, a proper diversity in the candidate solutions must be determined. Most existing diversity-maintenance mechanisms require a problem specific knowledge to setup parameters properly. This work proposes a method to control diversity of the population without explicit parameter setting. A self-adaptation mechanism is proposed based on the competition of preference characteristic in mating. It can adapt the population toward proper diversity for the problems. The experiments are carried out to measure the effectiveness of the proposed method based on nine well-known test problems. The performance of the adaptive method is comparable to traditional Genetic Algorithm with the best parameter setting.
