Knowledge obtained : [(AND p0 p1), (X (NOT (AND p0 (NOT p1)))), (X p0), (X p1), (X (X (NOT (AND p0 (NOT p1))))), (G (OR (NOT p0) p1))]
False Knowledge obtained : [(X (X (AND p0 p1))), (X (X (NOT (AND p0 p1)))), (X (X p0)), (X (X (NOT p0))), (X (X p1)), (X (X (NOT p1))), (F (NOT p1)), (F (NOT p0)), (F (NOT (AND p0 p1)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 6 factoid took 20 ms. Reduced automaton from 2 states, 4 edges and 2 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
