Computed a total of 11 stabilizing places and 11 stable transitions
Detected a total of 11/63 stabilizing places and 11/58 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/4 atomic propositions.
Knowledge obtained : [(AND (NOT p2) p0 (NOT p3) (NOT p1)), (X p0), (X (NOT (AND (NOT p2) (NOT p0)))), (X (X (NOT p3))), (X (X (AND (NOT p2) (NOT p1)))), (F (OR (G p1) (G (NOT p1))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(X p0)
Knowledge based reduction with 6 factoid took 127 ms. Reduced automaton from 5 states, 7 edges and 4 AP to 1 states, 0 edges and 0 AP.
