线性规划问题是指在线性约束条件下求线性目标函数的最值问题,其思想精髓是在可行域内根据目标函数的几何意义求出目标函数的取值范围.在函数与方程、不等式、解析几何、概率中广泛存在着求参数的取值范围问题,这些范围问题均可以用线性规划的思想求解,而且求解的过程简捷明快. The linear programming problem refers to the problem of finding the maximum value of the linear objective function under the linear constraints. The essence of the idea is to find the range of the objective function in the feasible region according to the geometric meaning of the objective function. In the function and equation, inequality, analytical geometry In both probability and probabilities, there are a wide range of problematic parameters. These range problems can be solved with the idea of ​​linear programming, and the solution process is simple and straightforward.
