2024 Elsevier LtdThis study introduces an arc-flow formulation and the first branch-and-price-and-cut (BPC) algorithm designed to solve the bin-packing problem with fragile objects (BPPFO). This variant of the bin-packing problem originates in the field of telecommunications, particularly in ...
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 ...

For many VRPs, the pricing problem of a branch-price-and-cut algorithm is highly complex and, to alleviate this difficulty, a relaxed pricing problem is used. In this paper, we introduce a new paradigm, called selective pricing, that can be applied in this context to improve the solution ...
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 ...
