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 (NOT p1) (NOT p2)), (X (NOT (AND p0 p1))), (X (AND p0 (NOT p1))), (X (NOT (AND (NOT p0) (NOT p1)))), (X (NOT (AND (NOT p0) p1))), (X (NOT p1)), (X (X (NOT (AND p0 p1)))), true, (X (X (AND p0 (NOT p1)))), (X (X (NOT (AND (NOT p0) (NOT p1))))), (X (X p0)), (X (X (NOT (AND (NOT p0) p1)))), (X (X (NOT p1))), (F (G p0)), (F (G (NOT p1))), (F (G (NOT p2)))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(F (G (NOT p2)))
Knowledge based reduction with 16 factoid took 401 ms. Reduced automaton from 9 states, 21 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
