Computed a total of 4 stabilizing places and 5 stable transitions
Detected a total of 4/17 stabilizing places and 5/33 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/1 atomic propositions.
Knowledge obtained : [(NOT p0), (X p0), (X (X (NOT p0))), (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 25 ms. Reduced automaton from 1 states, 1 edges and 1 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
