中文说明：这是一个遗传算法在函数求解方面的简单应用，虽然是个简单应用但是体现出了遗传算法在求解问题时的特点，如果在多个变量的情况下，它的优势会更明显，但是应该明白一点，就是遗传算法求解问题，不会得到一个精确的解，只是一个近似解，并且程序每次运行的结果可能会不同，这也算是遗传算法的特点，如果要求精确解的时候，这就是一个缺点，但是遗传算法的优势在一些大规模问题上是很明显的。
English Description：
This is a genetic algorithm in function solution aspects of simple application, although is a simple application but reflected out has genetic algorithm in solution problem Shi of features, if in multiple variable of situation Xia, it of advantage will more obviously, but should understand point, is genetic algorithm solution problem, does not get a precise of solutions, just a approximate solutions, and program each run of results may will different, this also is genetic algorithm of features, if requirements precise solutions of when, this is a shortcomings, But the advantage in some large-scale problems of genetic algorithms is very obvious.
