general-purpose cutting planes; a cutting plane algorithm for CSP was tested in [28, 2]. A pure cutting plane approach appeared almost equally effective to branch-and-price for CSP with a single stock length [2]. In 2CP, the objective function has its values among integer combinations ...

Then we investigate the associated polytope and introduce several classes of valid inequalities. Based on these results, we devise a Branch-and-Cut-and-Price algorithm for the problem and present an extensive computational study. This is also be compared with a Branch-and-Cut algorithm of the ...

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 ...

The resulting branch-and-cut-and-price algorithm can solve to optimality all instances from the literature with up to 135 vertices. This more than doubles the size of the instances that can be consistently solved. 机译:容量车辆路径问题(CVRP)的最佳精确算法已基于分支切线或拉格朗日松弛/列生成。
