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 to tighten the linear programming relaxations. Note that if cuts are only used to tighten...

Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten the linear programming relaxations. Note that if cuts are only used to tighten the initial LP relaxation, the algorithm is called cut and branch.[1] 02 总体描述 前面说过,branch and cut其实还是和br...
Moreover, we investigate the related polyhedron and describe several valid inequalities. We also devise separation routines for these inequalities. Based on this, we propose a Branch-and-Cut algorithm for the problem along with an extensive computational study showing the effectiveness of our approach...
Note that if cuts are only used to tighten the initial LP relaxation, the algorithm is called cut and branch.[1] 02 总体描述 前面说过,branch and cut其实还是和branch and bound脱离不了干系。其实是有很大干系的。在应用branch and bound求解整数规划问题的时候,如下图(好好复习一下该过程): 假如,...

We give integer programming formulations and valid inequalities for the different versions of the problem, solve them using a branch-and-cut algorithm, and discuss computational results. Some of the new inequalities can be used also to solve other problems in the literature, like the plant cycle ...
