This might not only cut off the auxiliary solution, but also the solution we originally wanted to separate. We discuss and extend Range's ideas to enhance the separation procedure. In particular, we present alternative heuristics and consider additional valid inequalities strengthening the original LP...

Sophisticated branch-cut-and-price (BCP) algorithms for some of the most classical VRP variants now solve many instances with up to a few hundreds of customers. However, adapting and reimplementing those successful algorithms for other variants can be a very demanding task. This work proposes a...
after a drug is developed, its developer can patent it and sell it at any price he wants. However, after a certain period, the rights to the drug wear off and any authorized seller can make it. This is what’s called a generic drug. Because there are so many more generic...
This engineered wood can be cut and shaped to fit various formwork designs, allowing for versatility in configuration and application. Its adaptability means that it can be utilized in a wide range of projects, from residential buildings to large-scale commercial structures, making it a favorite ...
And frankly the idea that they are price gorging is very silly. Back when I first started gaming, 30 identical plastic halbardiers cost somewhere in the region of £40(and £40 was a considerably larger amount of money back then) They where not even great models, but they still rep...

branch & price & cutCrew scheduling is a highly complex combinatorial problem that has substantial and consequential economic importance in practice. Although the core structure of the problem is the same in many different areas like urban transportation, airlines etc, the specific problem instances ...
We report on experiments with turning the branch-price-and-cut framework SCIP into a generic branch-price-and-cut solver . That is, given a mixed integer program (MIP), our code performs a Dantzig-Wolfe decomposition according to the user's specification, and solves the resulting re-...
