Decomposition Methods for Global Solutions of Mixed-Integer Linear Programs

This paper introduces two decomposition-based methods for two-block mixed-integer linear programs (MILPs), which break the original problem into a sequence of smaller MILP subproblems. The first method is based on the l1-augmented Lagrangian. The second method is based on the alternating direction method of multipliers. When the original problem has a block-angular structure, the subproblems … Read more
