通过自然选择、遗传、变异等作用机制，实现各个个体的适应性的提高。这一点体现了自然界中"物竞天择、适者生存"进化过程。1962年Holland教授首次提出了GA算法的思想，从而吸引了大批的研究者，迅速推广到优化、搜索、机器学习等方面，并奠定了坚实的理论基础。-Individuals through the mechanism of natural selection, genetic mutation, adaptation to improve. This is evidenced by the evolution process of " natural selection, survival of the fittest"　in nature. Holland professor in 1962 first proposed the idea of ​ ​ the GA algorithm, which attracted a large number of researchers quickly extended to optimization, search, machine learning, and has laid a solid theoretical foundation.
