Skipping Parikh replay, no witness traces provided.
Found 1 invariant AP formulas.
Knowledge obtained : [(AND p0 p1), (X (X p0)), (G (OR p0 p1))]
False Knowledge obtained : [(F (NOT p1)), (F (NOT p0))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 3 factoid took 12 ms. Reduced automaton from 6 states, 7 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
