Query: VPSolver 3: Multiple-choice Vector Packing Solver   VPSolver is a vector packing solver based on an arc-flow formulation with
graph compression. In this paper, we present the algorithm introduced in
VPSolver 3.0.0 for building compressed arc-flow models for the multiple-choice
vector packing problem.
