Model with wrong results

Open the attached model 

Verify the probability of reaching Process.GOAL - this is >= 0.9.. 

Use the model checker to check if Process.GOAL is reachable - FALSE

As SMC has made runs that hit Process.GOAL, Process.GOAL must be reachable.

I think in this model the model checker is not capable of verifying the model, and it should give an error message.

Tested in UPPAAL stratego and Uppaal 4.1.19 - none of them works
Comment 1 Marius Mikučionis 2015-09-30 11:51:08 CEST
"E<> Process.GOAL" should refuse to verify such model in the first place.
