Computed a total of 27 stabilizing places and 258 stable transitions
Detected a total of 27/27 stabilizing places and 258/260 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 3/3 atomic propositions.
Knowledge obtained : [(AND p0 (NOT p1) (NOT p2)), (X (NOT (AND (NOT p0) (NOT p1)))), (X (NOT (AND (NOT p0) p1))), (X p0), (X (NOT p1)), (F (OR (G p0) (G (NOT p0)))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p2) (G (NOT p2))))]
False Knowledge obtained : [(X (X (NOT p1))), (X (X p1))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 8 factoid took 15 ms. Reduced automaton from 9 states, 19 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).

Detected a total of 27/27 stabilizing places and 258/260 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 2/2 atomic propositions.
Knowledge obtained : [(AND p1 p0), (X (NOT (AND (NOT p0) (NOT p1)))), (X p1), (X (NOT (AND p0 (NOT p1)))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : [(X p0), (X (NOT p0)), (X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge (Minato strategy)
