Computed a total of 8 stabilizing places and 32 stable transitions
Detected a total of 8/42 stabilizing places and 32/196 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/2 atomic propositions.
Knowledge obtained : [(AND p1 p0), (X (NOT (AND (NOT p0) (NOT p1)))), (X (NOT p0)), (X p1), (X (X p1)), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 6 factoid took 16 ms. Reduced automaton from 3 states, 3 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
