Computed a total of 26 stabilizing places and 28 stable transitions
Detected a total of 26/1506 stabilizing places and 28/1929 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/3 atomic propositions.
Knowledge obtained : [(AND p0 p2 p1), (X p0), (X (X p1)), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 4 factoid took 10 ms. Reduced automaton from 5 states, 7 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
