遗传算法是一种模拟自然界生物进化的搜索算法，由于它简单易行，鲁

棒性强，尤其是其不需要专门的领域知识而仅用适应度函数作评价来指导搜

索过程，从而使它的应用范围极为广泛，并且己在众多领域得到了实际应用，

取得了许多令人瞩目的成果，引起广大学者和工程人员的关注。- The genetic algorithm is a kind of searching method which simulates the

natural evolution. It is simple and easy to implement, especially it do not need

the special field knowledge, so it has been using in very broad fields. Now the

genetic algorithm has got a lot of fruits and more scholars begin to pay attention

to it.
