He was not able to explain the nature of this optically inactive isomer, but the Le Bel–van't Hoff theory led to assignment of the structure C (Fig. 2) to this stereoisomer. It has the same connectivity (constitution) as A and B but differs in configuration. The reason for its lack...
所以在初始情况下,我们发现,该目标函数是一个非线性的,也就是bi-linear的。 直接使用Gurobi求解该模型也是可以的,但是效率应该会比求解MIP版本的低一些。 我们这里还是使用前文介绍的KKT条件的办法来求解 \mathbf{SP_2}。 我们写出KKT条件(注意,互补松弛的部分一定要是写成 \geqslant 0 的形式的左端项) \begin{...
