列生成算法通常被应用于求解大规模整数规划问题的分支定价算法(branch-and-price algorithm)中,其理论基础是由Danzig等于1960年提出。当求解一个最小化问题时,列生成算法主要的作用是为每个搜索树节点找到一个较优的下界(lower bound)。本质上而言,列生成算法就是单纯形法的一种形式,是用来求解线性规划问题的。列...
4 - Column Generation Algorithm and Indexed Shortest Path ProblemLei, Peng
经过小编的不断努力和修正,Column Generation + ESPPRC+ pulse algorithm的内容终于写完了。此过程真是充满曲折啊,希望大家看完多多支持一下。 运行说明 关于这部分的代码,我们提供两个版本。 第一个版本来自GitHub,是一个叫Seminar的国外大神写的。 他的子问题采用上一篇推文介绍的模型,找一条reduced cost最短的路...

We analyze the convergence and the complexity of a potential reduction column generation algorithm for solving general convex or quasiconvex feasibility problems defined by a separation oracle. The oracle is called at the analytic center of the set given
We also study, using an extensive computational experience, the impact of enriching our proposal with additional inequalities in a branch-and-cut-and-price algorithm, which has revealed the importance of supplementing our column generation algorithm with cuts to improve its performance. ...
