说明：  遗传算法是解决搜索问题的一种通用算法，对于各种通用问题都可以使用。 首先组成一组候选解，依据某些适应性条件测算这些候选解的适应度， 根据适应度保留某些候选解，放弃其他候选解。 对保留的候选解进行某些操作，生成新的候选解。
(Genetic algorithm is a general algorithm for solving search problems, and it can be used for all kinds of general problems. First, a set of candidate solutions is formed to estimate the fitness of these candidates according to some adaptive conditions, and to reserve some candidate solutions according to the fitness degree, and to give up other candidate solutions. Some candidate solutions are preserved to generate new candidate solutions.)
