A novel genetic algorithm based on cure mechanism of traditional Chinese medicine

Abstract

Enlightened by traditional Chinese medicine theory, a novel genetic algorithm (CMGA), which applies two types of treatment methods of "bu" and "xie" and dialectical treatment principle of traditional Chinese medicine theory to canonical GA, is proposed. The core of CMGA lies on constructing a cure operator, which is dynamically assembled with "bu" operation that replaces normal genes with eugenic genes and "xie" operation that replaces abnormal genes with normal genes. The main idea underlying CMGA is to give full play to the role of guidance function of knowledge to the evolutionary process through the cure operator. The simulation test of TSP shows that CMGA can restrain the degeneration and premature convergence phenomenon effectively during the evolutionary process while greatly increasing the convergence speed. © Springer-Verlag Berlin Heidelberg 2005.
