Computed a total of 46 stabilizing places and 46 stable transitions
Detected a total of 46/158 stabilizing places and 46/158 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/3 atomic propositions.
Knowledge obtained : [(AND (NOT p1) p0 p2), (X (NOT (AND p1 (NOT p0) p2))), (X (NOT (AND (NOT p1) (NOT p0) p2))), (X (NOT (AND p1 (NOT p0) (NOT p2)))), (X (NOT (AND (NOT p1) (NOT p0) (NOT p2)))), (X (X (NOT (AND p1 (NOT p0) p2)))), (X (X (NOT (AND (NOT p1) (NOT p0) p2)))), (X (X (NOT (AND p1 (NOT p0) (NOT p2))))), (X (X (NOT (AND (NOT p1) (NOT p0) (NOT p2))))), (F (OR (G p2) (G (NOT p2))))]
False Knowledge obtained : []
Property proved to be true thanks to conjunction of knowledge (Minato strategy)
Knowledge based reduction with 10 factoid took 136 ms. Reduced automaton from 3 states, 9 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
