代码说明：

数学建模竞赛中很多问题都和数学规划有关，可以说不少的模型都可以归结为一组不等式作为约束条件、几个函数表达式作为目标函数的问题，遇到这类问题，求解就是关键了，列举规划后用Lingo、Lindo等软件来进行解决比较方便。(Many problems in mathematical modeling contest are related to mathematical programming. It can be said that many models can be reduced to a set of inequalities as constraints and several functional expressions as objective functions. Solving these problems is the key. It is more convenient to use Lingo, Lindo and other software to solve these problems after enumerating the planning)

BP
BP神经网络：是一种按误差逆传播算法训练的多层前馈网络，是目前应用最广泛的神经网络模型之一。BP网络能学习和存贮大量的输入-输出模式映射关系，而无需事前揭示描述这种映射关系的数学方程。它的学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小。BP神经网络模型拓扑结构包括输入层（input）、隐层(hide layer)和输出层(output layer)。(BP neural network: a Press the front back propagation algorithm to train multilayer feedforward network is one of the most widely used neural network model. BP network can learn and store large amounts of input- output mode mappings without prior reveal mathematical equations that describe this map. It' s learning rule is to use the steepest descent method, through a reverse spread to constantly adjust the network weights and thresholds, so that the minimum squared error of the network. BP neural network topology, including the input layer (input), hidden layer (hide layer) and output layer (output layer).)
