线性规划问题的描述. 一个问题要能转化为线性规划问题，首先要有若干个线性约束条件，并且所求的目标函数也应该是线性的。. 那么，最容易也最常用的描述方法就是标准型。. 我们以《算法导论》中线性规划一节提出的问题为例：. 假如你是一位政治家 ...60 = 1200. 10 = 200 : The cost per batch of 100 type 1 chips is $1900. The current sale price of each batch of 100 type 1 chips is $2000 + $1900 = $3900, or equivalently, $39 per chip. We do not produce type 1 chip in our optimal production mix, so the breakeven sale price must be greater than $39 per chip. The quadratic equations xizi = 0 and siwi = 0 are called the complementarity conditions for the linear program; the other (linear) equations are called the feasibility conditions. The quantity. xTz + sTw. is the duality gap, which measures the residual of the complementarity portion of F when (x,z,s,w) ≥ 0.
