Computed a total of 22 stabilizing places and 26 stable transitions
Detected a total of 22/163 stabilizing places and 26/128 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/3 atomic propositions.
Knowledge obtained : [(AND p0 p1 p2), (X (NOT (AND (NOT p0) p1))), (X (NOT (AND (NOT p0) (NOT p1)))), (X p0), (X (NOT p1)), (X (X p2)), (F (OR (G p1) (G (NOT p1))))]

Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 7 factoid took 23 ms. Reduced automaton from 5 states, 9 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
