Endless calculation with following model about pict HOT 1 CLOSED

Unfortunately, this is by design. There's a part of the PICT algorithm that takes exponential time. Under normal circumstances--when models are less complex--it takes small enough amount of time for no one to notice but when the complexity of constraints increases, it becomes noticeable. It is not an endless loop, the work is happening it is just taking a really long time.

The best suggestion I can offer is to simplify the model somehow. That is still maintain its completeness and correctness but maybe try to express fewer features in a single model and create another one to take care of those.
