遗传算法( genetic algorithms, 简称GA )是根据自然界的“物竞天择, 适者生存”现象而提出来的一种随机搜索算法, 是霍兰德( Holland) 于1975 年在他的著作《Adaption in Natural and artificial Systems》中首次提出来的。此算法将优化问题看作是自然界中生物的进化过程, 通过模拟大自然中生物进化过程中的遗传规律, 来达到寻优的目的。-Genetic algorithms (genetic algorithms, referred to as GA) is based on nature s　natural selection, survival of the fittest　phenomenon and proposed a random search algorithm, is a Holland (Holland) in 1975 in his book　Adaption in Natural and artificial Systems　was first put forward. This algorithm will be viewed as optimization problems is a natural biological process of evolution, through the analog nature of biological evolution in the process of inheritance, to achieve the purpose of optimization.
