Relaxed versions of a base model are solved using an optimization package and, if binary variables have fractional values or if some of the relaxed constraints are violated in the solution, cutting planes are added. Once no more cuts can be added, branch and bound is used. The method for ...

We propose a branch-and-cut (B&C) method for solving general MAP-MRF inference problems. The core of our method is a very efficient bounding procedure, which combines scalable semidefinite programming (SDP) and a cutting-plane method for seeking violated constraints. In order to further speed up...
A branch-and-cut approach for Benders’ decomposition has been implemented within the constraint integer programming solver SCIP using a plugin-based design to allow for a wide variety of extensions and customisations to the algorithm. The effectiveness of the Benders’ decomposition algorithm and ...
This NP-hard problem is formulated as an Integer Linear Program and solved by an exact branch-and-cut technique, based on strong cutting planes. We start with very few constraints and use separation procedures to detect the violated constraints. The method and its implementation are tested on a...

Branch and cut methods for integer programming problems solve a sequence of linear programming problems. Traditionally, these linear programming relaxations have been solved using the simplex method. The reduced costs available at the optimal solution to a relaxation may make it possible to fix variable...

In order to keep master green, we can run a pipeline on the state that master would be in after the merge - by combining the source and target branch into a new ref, then running a pipeline on that ref, we can better test that the combined result is also valid (at least moreso th...
