Detected a total of 1890/4489 stabilizing places and 2618/7794 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 3/3 atomic propositions.
Knowledge obtained : [(AND p0 p1 p2), true, (X (X p2)), (X (X p0)), (F (OR (G p0) (G (NOT p0)))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p2) (G (NOT p2))))]
False Knowledge obtained : [(X (X (NOT p1))), (X (X p1))]
Knowledge sufficient to adopt a stutter insensitive property.
Knowledge based reduction with 7 factoid took 399 ms. Reduced automaton from 7 states, 13 edges and 3 AP (stutter sensitive) to 4 states, 7 edges and 2 AP (stutter insensitive).
