Knowledge obtained : [(AND (NOT p0) p2 p1), (X (NOT p2)), (X (NOT p0)), (X (NOT (AND (NOT p0) (NOT p2) (NOT p1)))), (X (AND (NOT p0) (NOT p2))), (X p1), (X (X (NOT p0))), (X (X (NOT (AND (NOT p0) (NOT p2) (NOT p1))))), (X (X (NOT (AND (NOT p0) p2 (NOT p1))))), (X (X p1)), (F (OR (G p0) (G (NOT p0)))), (F (G p2)), (F (G p1))]
False Knowledge obtained : [(X (X p2)), (X (X (NOT p2))), (X (X (AND (NOT p0) (NOT p2)))), (X (X (NOT (AND (NOT p0) (NOT p2)))))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 13 factoid took 20 ms. Reduced automaton from 4 states, 8 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
