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)
