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 ...

This work presents a sophisticated exact algorithm for the TSPHS, a Branch-Cut-and-Price (BCP) algorithm that includes and adapts several features found in state-of-the-art algorithms for vehicle routing. In that algorithm, columns correspond to possible salesperson day trips; subtour elimination ...
今天发现了一个VRP领域的大牛做的PPT,关于Branch and price and cut算法求解传统VRP问题以及VRPTW的。 详细推文可参考公众号往期的介绍。 PPT有92页之多,详细介绍了VRP问题的建模以及算法的各个知识点。 值得分享,大家可以收藏一下,说不定以后能用得上呢。哈哈哈哈! 获取方式在后台回复【BPCVRP】不包括【】即可下...
