TIMINGS:

Total run time for the heuristic = 324922 ms
The total time to calculate the lower bounds with CPLEX = 3685 ms
The total time to calculate the upper bounds with CPLEX = 125 ms
The total time to create the lower bound problems = 6825 ms
The total time to read the lower bound solutions = 2336 ms
The total time to check if computing the upper bounds are needed = 15 ms
The total time to create the upper bound problems = 93 ms
