WebDec 16, 2024 · Dual bounds of integer programming problems. I often read in papers when branch-and-X algorithms are used to solve mixed integer programming problems, that the lower bound (in the minimization case) obtained from solving a linear programming relaxation at each branching node, is called a dual bound. Consequently, the gap … WebMixed Integer Programming Basics. The problems most commonly solved by the Gurobi Parallel Mixed Integer Programming solver are of the form: Objective: minimize c T x.
