Then you saw how to use a simple MathProg program to solve it using sets, parameters, constraints, decision variables, and an objective (target) function.

接下来我们了解了如何使用一个简单的MathProg程序来使用集合、参数、约束、决策变量和目标函数来解答这个问题。

The operational efficiency of program is improved when the parameters are transferred by dispersed document or sparse matrix and the variables of different forms are defined reasonably.

指出通过分散文档或稀疏矩阵的形式进行参数传递，对不同形式变量进行合理的定义，可提高程序的运行效率。
