Starting from a restricted 0-1 mixed-integer program, the branch-and-bound algorithm may, at any node of the search tree, selectively relax, or unfix, previously fixed variables, restrict, or fix, additional variables, or unfix and fix variables at the same time using dual or structural ...
Parallelism As noted at the beginning of this discussion, the Gurobi MIP solver runs in parallel. The main source of parallelism is the fact that different nodes in the MIP tree search can be processed independently. As is probably apparent, however, the root node presents limited parallelism op...
This kind of tightening can be critical to the solution of an integer program, and is one of the reasons that MIP presolve is an important tool in the solution on MIPs, much more so than LP presolve in the solution of linear programs. Cutting Planes Let us now consider the idea of ...
We formulate the verification of piecewise-linear neural networks as a mixed-integer program. On a representative task of finding minimum adversarial distortions, our verifier is two to three orders of magnitude quicker than the state-of-the-art. We achieve this computational speedup via tight ...

Input: mixed-integer program. Incumbent solution = φ. List of unexplored nodes = φ. 1. Root node is the original model. Solve the LP relaxation of the root node. If LP relaxation is infeasible, exit with infeasible outcome. If LP relaxation is integer-feasible, exit with relaxation ...

MIPaaL: Mixed Integer Program as a Layer Machine learning components commonly appear in larger decision-making pipelines; however, the model training process typically focuses only on a loss that measures accuracy between predicted values and ground truth values. Decision-focused learning explicitly ...
