Computed a total of 216 stabilizing places and 211 stable transitions
Detected a total of 216/313 stabilizing places and 211/257 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 2/3 atomic propositions.
Knowledge obtained : [(AND p0 p1 p2), (X p2), (X (NOT (AND (NOT p0) p1))), (X (NOT (AND (NOT p0) (NOT p1)))), (X p0), (X p1), (X (NOT (AND (NOT p0) (NOT p1) p2))), (X (X p2)), (X (X (NOT (AND (NOT p1) p2)))), (X (X (AND p1 p2))), (X (X p1)), (F (OR (G p0) (G (NOT p0)))), (F (OR (G p2) (G (NOT p2))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 13 factoid took 13 ms. Reduced automaton from 6 states, 9 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
