摘    要:针对简单遗传算法中容易出现的早熟性收敛问题,采用“自适应算子”和“移民策略”相结合的办法对简单遗传算法进行改进,并且采取了“加速迭代”的操作,最后通过对Schaffer函数的计算表明,本文改进的遗传算法在保证全局收敛的同时有效地避免了早熟性收敛的发生。

关 键 词:遗传算法  优化  早熟性收敛

Abstract:In spite of the advantage of Genetic Algorithm (GA), premature is one of the serious problems in practice. In this paper, an improved GA based on adaptive operators and immigrant method is studied to solve the premature problem, and a method to accelerate circulation is adopted. The simulating results indicate that the improved GA has the characters of high convergent efficiency and quality of solutions in large search space.
Keywords:Genetic algorithm  Optimization  Premature
