现在用在大规模求解IP和MIP的精确算法,比如branch and price和branch and cut算法都是基于分支定界算法框架而设计的。 比如branch and price算法,是在基本的branch and bound的基础上,在求解子节点松弛问题的时候采用列生成的方法,一列一列的添加变量,让问题规模从小变大,而别的都没变。原始的基础的branch and bo...

Branch-and-cut-and-priceSummary: Assume that a connected undirected edge weighted graph $G$ is given. The Degree Constrained Minimum Spanning Tree Problem (DCMSTP) asks for a minimum cost spanning tree of $G$ where vertex degrees do not exceed given pre-defined upper bounds. In this paper,...
分支与价格与切割算法
The experiments compare the new algorithms among themselves and also against the best algorithms currently available in the literature. As an outcome of them, one of the new algorithms stands out on top. 展开 关键词: Degree Constrained Spanning Tree Branch-and-cut Branch-and-cut-and-price ...
In this work, we present an optimal algorithm, BCP, that hybridizes both approaches using Branch-and-Cut-and-Price, a decomposition framework developed for mathematical optimization. We formalize BCP and compare it empirically against CBSH and CBSH-RM, two leading search-based solvers. Conclusive ...

This work proposes a Branch-cut-and-price (BCP) approach for the Vehicle Routing Problem with Simultaneous Pickup and Delivery (VRPSPD). We also deal with a particular case of the VRPSPD, known as the Vehicle Routing Problem with Mixed Pickup and Delivery. The BCP algorithm was tested 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 ...
