遗传算法（Genetic Algorithm）是一类借鉴生物界的进化规律（适者生存，优胜劣汰遗传机制）演化而来的随机化搜索方法。它是由美国的J.Holland教授1975年首先提出，其主要特点是直接对结构对象进行操作，不存在求导和函数连续性的限定；具有内在的隐并行性和更好的全局寻优能力；采用概率化的寻优方法，能自动获取和指导优化的搜索空间，自适应地调整搜索方向，不需要确定的规则。遗传算法的这些性质，已被人们广泛地应用于组合优化、机器学习、信号处理、自适应控制和人工生命等领域。它是现代有关智能计算中的关键技术。-Genetic Algorithm (Genetic Algorithm) is a class learn the laws of evolution of the biosphere (survival of the fittest, survival of the fittest genetic mechanism) evolved random search method. By U.S. J.Holland Professor in 1975 first proposed, whose main characteristic is to operate directly on the structure of the object, there is no derivation and limited function continuity　internal implicit parallelism and better global optimization capability　 using a probability optimization methods can automatically access and guidance to optimize search space adaptively adjust the search direction, the rules do not need to be determined. These properties of the genetic algorithm has been widely used in combinatorial optimization, machine learning, signal processing, adaptive control and artificial life. It is a key technology in the modern about intelligent computing.
