TIMINGS:

Total run time for the heuristic = 558031 ms
The total time to calculate the lower bounds with CPLEX = 3710 ms
The total time to calculate the upper bounds with CPLEX = 2856 ms
The total time to create the lower bound problems = 5831 ms
The total time to read the lower bound solutions = 767 ms
The total time to check if computing the upper bounds are needed = 0 ms
The total time to create the upper bound problems = 3707 ms
The total time to read the upper bound solutions = 676 ms 

The best upper bound found = 59367.434458, the best lower bound found = 43014.829672
Therefore the duality gap is 38.016203%
