inf = infinity
RLB = lower bound at root node
BLB = best known lower bound
BUB = best known upper bound; equal to "?" if no feasible solution found
GAP(%) = (BUB-BLB)/BUB; equal to "-" when infeasible
Time given in seconds on a Pentium 4, 3.8Ghz, 4GB RAM, under GNU/Linux

* NOTE: Instance 3 had to have its machine capacity raised to 29 to become feasible.
