Inference results for university.mln

Summary: results under Gibbs sampling quite different from results under MC-SAT.

In all the following tests university.db is empty.

Gibbs sampling

Command:
infer -i university.mln -r university.results -e university.db -ow student,professor -q 'advisedBy(Gail,Glen),inPhase(Hanna,phase)' -p -maxSteps 20000 -burnMaxSteps -1

Output:
Done Gibbs sampling. 20000 samples per pred per chain (didn't converge at total of 200000 samples per pred)
Time taken for Gibbs sampling = 1.87 secs
total time taken = 3.32 secs
Results in university.results (5 repetitions):

Command (querying only advisedBy(Gail,Glen)):
infer -i university.mln -r university.results -e university.db -ow student,professor -q 'advisedBy(Gail,Glen)' -p -maxSteps 20000 -burnMaxSteps -1

Output:
