现在用在大规模求解IP和MIP的精确算法,比如branch and price和branch and cut算法都是基于分支定界算法框架而设计的。 比如branch and price算法,是在基本的branch and bound的基础上,在求解子节点松弛问题的时候采用列生成的方法,一列一列的添加变量,让问题规模从小变大,而别的都没变。原始的基础的branch and bo...

Our branch-and-cut-and-price algorithm relies upon a path-based formulation, where each column in the master problem repre- sents a sequence of customer visits between two recharge stations instead of a whole route. This allows for massive decomposition, and parallel implementation of the pricing...
branch-and-price-and-cutIn this article, we propose a branch‐and‐price‐and‐cut (BPC) algorithm to exactly solve the manpower routing problem with synchronization constraints (MRPSC). Compared with the classical vehicle routing problems (VRPs), the defining characteristic of the MRPSC is ...

(DCMSTP) asks for a minimum cost spanning tree ofGwhere vertex degrees do not exceed given pre-defined upper bounds. In this paper, three exact solution algorithms are investigated for the problem. All of them are Branch-and-cut based and rely on the strongest formulation currently available ...
