Complete graph has no SCC; deadlocks are unavoidable. place count 14 transition count 65
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 (NOT p1) p2), (X (X p2)), (F (G (NOT p1))), (F (G (NOT p2)))]
False Knowledge obtained : [(X p1), (X (NOT p1)), (X (X p1)), (X (X (NOT p1)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 4 factoid took 14 ms. Reduced automaton from 5 states, 6 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
