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) (NOT p0)), (X (NOT p0)), (X (NOT p1)), (X (X (NOT p0))), (X (X (NOT p1))), (F (G (NOT p1))), (F (G (NOT p0)))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(X (X (NOT p0)))
Knowledge based reduction with 7 factoid took 146 ms. Reduced automaton from 3 states, 4 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
