线性规划是高中试验教材新增内容之一,解这类问题,通常都要先利用线性约束条件作出可行域,然后根据几何意义找到目标函数的最优解,但这种方法比较麻烦,既要画线,又要找点,比较费时.如果我们从线性约束条件入手,利用不等式的基本性质,将条件不等式进行等价变形与合理运算,往往会 Linear programming is one of the newest contents of high school teaching materials. To solve such problems, it is usually necessary to make feasible domain by using linear constraints first, and then find the optimal solution of the objective function according to the geometric meaning. However, this method is too cumbersome Draw lines, but also to find something, more time-consuming.If we start with the linear constraints, the basic nature of the use of inequalities, the inequalities of inequalities and equivalent computing deformation, often
