解析条件极值

Analysis of Conditional Extreme Value

条件极值在国民生产中有广泛的应用,例如,布局问题,分派问题等等。一些特殊的条件极值问题,可以转化为极值问题;目标函数和约束条件均为线性,可用单纯形法求解;二次以上的条件极值,可用Lagrange乘子法;Lagrange乘子法在求解条件极值问题上有重要的应用。

In the national production,the conditional extreme value has the widespread application, for example, the layout question, distribution question and so on. Some special Conditional extreme value problems may be transformed into the Extreme value problem;When the objective function and the constraint condition is a linearity ,the problem may be solved by simplex method; Lagrange multiplier solve the problem with more than two constraint conditions. The Lagrange multiplier has application in the solution of Conditional extreme value problem.
