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 ...
The optimization algorithm applies affine transform based interior point method and simplified branch bound method for reactive power optimization. 优化算法将仿射变换内点法与简化分枝定界法(内点 -分枝定界法 )综合应用于优化过程中 ,计算结果表明它是一种有效的无功优化算3...

and-cut method was introduced, the fundamental question concerned the termination and the complexity of the method. On the practical side, the optimization problem is reduced to adding some cutting planes. A variant ofbranch and cut, branch and price and cut (branch and price explained below),...
We derive strong valid inequalities and devise separation procedures for them. • Some of the valid inequalities generalize other inequalities in the literature. • The proposed branch-and-cut method succeeds in solving instances with up to 40 nodes. Abstract This paper approaches the problem of...
