Computed a total of 33 stabilizing places and 310 stable transitions
Detected a total of 33/33 stabilizing places and 310/312 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 3/3 atomic propositions.
Knowledge obtained : [(AND (NOT p2) (NOT p1) (NOT p0)), (X (NOT p2)), (X (NOT (AND (NOT p2) p1 (NOT p0)))), (X (NOT (AND (NOT p2) p1 p0))), (X (AND (NOT p2) (NOT p1))), (X (NOT p1)), (X (X (NOT (AND (NOT p2) p1 (NOT p0))))), (X (X (NOT (AND (NOT p2) p1 p0)))), (X (X (NOT (AND (NOT p2) p1)))), (F (OR (G p2) (G (NOT p2)))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : [(X p0), (X (NOT p0)), (X (X p2)), (X (X (NOT p2))), (X (X (AND (NOT p2) (NOT p1)))), (X (X (NOT (AND (NOT p2) (NOT p1))))), (X (X p0)), (X (X (NOT p0))), (X (X p1)), (X (X (NOT p1)))]
Property proved to be false thanks to negative knowledge :(X (X p1))
Knowledge based reduction with 12 factoid took 4200 ms. Reduced automaton from 6 states, 14 edges and 3 AP (stutter sensitive) to 1 states, 1 edges and 0 AP (stutter insensitive).
