WebIn our case, we can fathom Subproblem 1 because its solution is integral. The best integer solution found so far is stored as incumbent. The value of the incumbent is denoted by Z*. In our case, the first incumbent is (3, 3), and Z*=39. Z* is a lower bound for OPT(IP): OPT(IP) ≥ Z* . In our case, OPT(IP) ≥ 39. The upper bound is 41: OPT(IP) 41.
