We propose a mixed-integer programming model and a branch-price-and-cut-based exact algorithm to address this problem. To reduce the computation time, we design several acceleration strategies, including a combination of dynamic programming and calculus-based approximation for the pricing problem, and...
The problem is solved by means of a branch-and-price algorithm. The DSDVRPTW can indirectly model the C-SDVRP by defining the set of orders to associate with a customer as the set of all possibles subsets of commodities to deliver to him. In this paper, we focus on the exact solution...
branch and price其实是column generation和branch and bound的结合。为什么要结合呢?前面的文章中介绍过,column generation是求解大规模线性规划问题的,注意是线性规划问题,不是整数或者混合整数规划问题。 因此在用column generation求解VRPTW的Set-Partitioning Model的时候,需要先将决策变量由整数松弛为实数,详情参见: ...
branch and price求解VRPTW问题代码详解 一、前言 记得公众号很久之前推出过一个branch and price的概念推文,后来小编找到了部分(不完整)的代码,经过研究以后补齐了这部分代码,能够运行以后也分享了给大家。详情可以看: 干货| 10分钟带你掌握branch and price(分支定价)算法超详细原理解析)...
