Knowledge obtained : [(AND p1 p0), (X (NOT (AND (NOT p0) (NOT p1)))), (X (NOT (AND p0 (NOT p1)))), (X p0), (X p1), (X (X p1)), (X (X (NOT (AND (NOT p0) (NOT p1))))), (X (X (NOT (AND p0 (NOT p1))))), (X (X p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 9 factoid took 23 ms. Reduced automaton from 3 states, 4 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
