Branch and cut is a method of combinatorial optimization for solving integer linear programs (ILPs), that is, linear programming (LP) problems where some or all the unknowns are restricted to integer values. Branch and cut involves running a branch and bound algorithm and using cutting planes ...
回想一下,我们上面提到的incumbent概念。尽快找到好的incumbent,对快速求解MIP有非常重要的意义:incumbent的值越高,LP松弛的值越可能超过它(在最小化问题中),从而决定该节点不需要进一步branch(或者说cut掉)。 现在我们知道,在搜索树的某些节点上做一些额外的工作(heuristics)以找到更好的incumbent非常有价值的。找的方...

A numerical study is carried out of the branch and cut method adapted for solving the clique partitioning problem (CPP). The problem is to find a family of pairwise disjoint cliques with minimum total weight in a complete edge-weighted graph. The two particular cases of the CPP are ...

CMIPs are at present solved using the vanilla branch-and-bound method that solves continuous conic relaxations at the nodes of a branch-and-bound search tree. Branch-and-cut methods, that make use of the problem structure for removing fractional solutions of conic relaxations and thereby reducing...
