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 ...

When the relaxation in each node of a branch-and- bound tree is solved by column generation, one speaks of branch-and-price. Optionally, cutting planes can be added in order to strengthen the relaxation, and this is called branch- price-and-cut. We introduce the common concepts of ...
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...
