人工神经网络是一种应用类似于大脑神经突触联接的结构进行信息处理的数学模型。在工程与学术界也常直接简称为神经网络或类神经网络。神经网络是一种运算模型，由大量的节点（或称神经元）和之间相互联接构成。每个节点代表一种特定的输出函数，称为激励函数（activation function）。每两个节点间的连接都代表一个对于通过该连接信号的加权值，称之为权重，这相当于人工神经网络的记忆。网络的输出则依网络的连接方式，权重值和激励函数的不同而不同。而网络自身通常都是对自然界某种算法或者函数的逼近，也可能是对一种逻辑策略的表达。

遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。　　遗传算法是从代表问题可能潜在的解集的一个种群（population）开始的，而一个种群则由经过基因（gene）编码的一定数目的个体(individ
