Genetic algorithm is an artificial intelligence technology of self - organization and adaptation , which imitates natural organisms " evolutionary process and mechanism to solve problems . although the algorithm has been widely applied to the computer science , artificial intelligence , information technology and engineering projects , but it still suffers from performance deficiency . so more studies should be carried out to improve its performance because of its large value in theory research and practical application 遗传算法是模拟自然界生物进化过程与机制求解问题的一类自组织与自适应的人工智能技术,已广泛应用于计算机科学、人工智能、信息技术及工程实践,但在算法性能方面还有不足之处,因而对其进行改进研究具有理论意义和实用价值。
