Knowledge obtained : [(AND (NOT p2) (NOT p3) p0 (NOT p1)), (X (NOT p2)), (X (NOT p3)), (X (NOT (AND (NOT p2) p3 p0))), (X (NOT (AND (NOT p2) p3 (NOT p0)))), (X (X (NOT p3))), (X (X (NOT (AND (NOT p2) p3 p0 p1)))), (X (X (NOT (OR (AND (NOT p2) p3 (NOT p0)) (AND p3 (NOT p1)))))), (X (X (NOT p1))), (F (OR (G p3) (G (NOT p3))))]
False Knowledge obtained : [(X p0), (X (NOT p0)), (X (X p2)), (X (X (NOT p2))), (X (X p0)), (X (X (NOT p0)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 10 factoid took 27 ms. Reduced automaton from 4 states, 6 edges and 4 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
