TIMINGS:

Total run time for the heuristic = 308375 ms
The total time to calculate the lower bounds with CPLEX = 2958 ms
The total time to calculate the upper bounds with CPLEX = 31 ms
The total time to create the lower bound problems = 2339 ms
The total time to read the lower bound solutions = 641 ms
The total time to check if computing the upper bounds are needed = 0 ms
