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 : [p0, (X (X p0)), (F (G p0))]
False Knowledge obtained : [(X p0), (X (NOT p0))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 3 factoid took 13 ms. Reduced automaton from 1 states, 2 edges and 1 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
