遗传算法以一种群体中的所有个体为对象，并利用随机化技术指导对一个被编码的参数空间进行高效搜索。其中，选择、交叉和变异构成了遗传算法的遗传操作；参数编码、初始群体的设定、适应度函数的设计、遗传操作设计、控制参数设定五个要素组成了遗传算法的核心内容。(Genetic algorithm takes all individuals in a group as objects, and uses randomized technology to guide efficient search of a coded parameter space. Among them, selection, crossover and mutation constitute the genetic operation of genetic algorithm. Parameter coding, initial population setting, fitness function design, genetic operation design, and control parameter setting constitute five elements of the core content of genetic algorithm.)
