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 ...
We present an algorithm for globally minimizing a multivariate polynomial on a given polyhedron. Our approach is based on the Bernstein-Bezier representation of the polynomial on a simplex. We use global properties of the Bezier points to derive the lower bounds of the global minimum. We discuss...

In that algorithm, columns correspond to possible salesperson day trips; subtour elimination cuts, 2-path cuts, and limited-memory subset row cuts are separated. Computational results show that many medium-sized instances, having up to 75 clients and 20 hotels, can be solved to optimality, as ...

A Unified Branch-Price-and-Cut Algorithm for Multicompartment Pickup and Delivery Problems In this paper, we study the pickup and delivery problem with time windows and multiple compartments (PDPTWMC). The PDPTWMC generalizes the pickup and deliv... M Aerts-Veenstra,M Cherkesly,T Gschwind -...
synchronizationbranch-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 ...
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。
