Computed a total of 2 stabilizing places and 1 stable transitions
Knowledge obtained : [(NOT p0), (X p0)]
False Knowledge obtained : [(X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 13 ms. Reduced automaton from 2 states, 2 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
