Detected a total of 23700/29716 stabilizing places and 32952/44921 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 3/3 atomic propositions.
Knowledge obtained : [(AND p2 (NOT p1) p0), (X (NOT (AND (NOT p0) p1 (NOT p2)))), (X (NOT (AND (NOT p0) (NOT p1) (NOT p2)))), (X (X p2)), (X (X (NOT (AND p1 (NOT p2))))), (X (X (NOT (AND (NOT p1) (NOT p2))))), (F (OR (G p2) (G (NOT p2)))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(X (NOT (AND (NOT p0) (NOT p1) (NOT p2))))
Knowledge based reduction with 9 factoid took 173 ms. Reduced automaton from 4 states, 6 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
