Heuristic Miner not deterministic?
why is the Miner seem not deterministic?
I created a Petri Net in ProM 6.3 via Log and exported it to file.
After that I started ProM 5.0 and imported the log.
I added atrifical Start and End Events via Filter to the log.
Then I imported the petri net and connected it to the filtered log.
I started Analysis/Conformance Checker and clicked two times on "Start Analysis".
The results differ a little. For instance the Fitness: 0.890 ; 0.889.
Also the diagnostic token counter value vary: 7, 9, 6....
There is not much "randomness" but
its strange for me that the algorithm is a bit random.
