Complete graph has no SCC; deadlocks are unavoidable. place count 581 transition count 546
Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge (and all enablings converge to false).
Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge : F ( (Ga|G!a) & (Gb|G!b)...)
Knowledge obtained : [(AND p0 p1 (NOT p2)), (X p0), (X p1), (X (NOT (AND p1 p2))), true, (X (X (NOT (AND p1 p2)))), (X (X (NOT (AND (NOT p1) p2)))), (F (G p0)), (F (G p1)), (F (G (NOT p2)))]
False Knowledge obtained : [(X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge :(X (NOT (AND p1 p2)))
Knowledge based reduction with 10 factoid took 266 ms. Reduced automaton from 6 states, 9 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
