Study on Self-adjusting Genetic Algorithm

ZHUANG Jian, WANG Sunan (School of Mechanical Engineering, Xian Jiaotong University, Xian 710049, China)  
The selection operator, the corssover operator and the mutation operator of the genetic algorithm are deeply analyzed in the paper. Then, it is proved that the main reason of the premature phenomena is the selection operator. Based on the analysis, a self-adjusting gene migration genetic algorithm with the self-changeable mutation rate is designed. And the guideline of the population differentia is put forward. The probability of mutation is automatically changed by the population differentia. So the population diversity is kept and the premature phenomena are avoided. At last, the convergence of the algorithm is proved by the Markov-Chain. The experimental results indicate that it has the ability of the universal using and is suitable for the engineering calculation.
