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 遺傳算法是模擬自然界生物進(jìn)化過程與機(jī)制求解問題的一類自組織與自適應(yīng)的人工智能技術(shù),已廣泛應(yīng)用于計(jì)算機(jī)科學(xué)、人工智能、信息技術(shù)及工程實(shí)踐,但在算法性能方面還有不足之處,因而對(duì)其進(jìn)行改進(jìn)研究具有理論意義和實(shí)用價(jià)值。
