Hi,
I am building a maximization problem using CP solver (Python, Ubuntu 12.04) - right now it is very simple and can be summarized as a scheduling problem using binary [0,1] variables used to choose working slots. I have 5 working stations that can work in parallel. When I have aprox. 30 slots everything goes fine and the output is given in 3s.
When I insert a new batch with 7 more slots, firstly the program outputs all values correctly, very quickly, however, after that, it runs for aprox. 10 minutes until it is killed by the operational system, with the following output:
num_solutions: 1
failures: 99512403
branches: 199024802
WallTime: 509 s
[1]+ Killed python2.7 orch_bid3.py
Any suggestion of some obvious problem?
I can post the problem here if needed.
Thanks in advance.
