"NettetFact. The optimal objective value of the linear programming relaxation is an upper bound for the objective value of the integer program. Whatever the optimal integer solution is, its objective value is at most 23:5. (It could be equal, or it could be smaller. The integer program might even be infeasible, which we’ll often think of as an " - Integer programming branch and bound
