TIMINGS:

Total run time for the heuristic = 308047 ms
The total time to calculate the lower bounds with CPLEX = 2653 ms
The total time to calculate the upper bounds with CPLEX = 15 ms
The total time to create the lower bound problems = 2396 ms
The total time to read the lower bound solutions = 623 ms
The total time to check if computing the upper bounds are needed = 0 ms
The total time to create the upper bound problems = 16 ms
The total time to read the upper bound solutions = 0 ms 

The best upper bound found = 35981.000000, the best lower bound found = 35677.000000
Therefore the duality gap is 0.852090%
