自然选择

The genetic algorithm is a kind of self-adapting optimization method based on the mechanics of natural selection and evolution. It is appropriate to deal with the discrete and multi-variable combined optimization problem.

遗传算法是一种基于自然选择和进化机制而形成的一种自适应全局优化算法，它非常合适处理离散的、多变量的组合优化问题。

He suggested that bees which make hexagonal cells evolved in steps from bees that made round cells, under pressure from natural selection to economise wax.

This is somewhat the same argument of the neodarwinists: all evolution is the extrapolation of natural selection compounded.

"I think biologists could tell you this has something to do with natural selection — the person who acquires power becomes the alpha male," said Tom Fiedler, who teaches a course in press and politics at Harvard 's Kennedy School.

"生物学家会说这种现象跟自然选择有关。权力在握的男性成为物种优化的最佳选择，"哈佛大学肯尼迪学院的汤姆费德勒如是说。他在肯尼迪学院开了一门课，讲授媒体与政治的关系。
