线性规划基本模式是已知两个变量x,y的线性约束条件,求z=f(x,y)的范围.但是,常会遇到一些与线性规划似乎不相关的求最值(范围)的问题,其实,只要作深入分析,不难发现均能化归为线性规划问题去求解.本文列举八类这样的交汇问题进行剖析,与读者共赏.一、线性规划与函数交汇例1设二元一次不等式组 The basic linear programming model is a linear constraint known to the two variables x, y that finds the range of z = f (x, y), but often encounters some of the most significant (range) values ​​that seem unrelate to linear programming In fact, as long as making in-depth analysis, it is not difficult to find that all can be classified as linear programming problems to solve .This article lists eight kinds of such intersection problems to analyze and share with readers. First, the linear programming and function intersection example 1 set two Yuan once inequality group
