A Hierarchy of Bounds for Stochastic Mixed-Integer Programs

Sandikci, Burhaneddin - 2009

Strong relaxations are critical for solving deterministic mixed-integer programs. As solving stochastic mixed-integer programs (SMIPs) is even harder, it is likely that strong relaxations will also prove essential for SMIPs. We consider general two-stage SMIPs with recourse, where integer...
