Computed a total of 319 stabilizing places and 975 stable transitions
Detected a total of 319/1134 stabilizing places and 975/2591 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 2/2 atomic propositions.
Knowledge obtained : [(AND p0 p1), (X p0), (X p1), (X (X p0)), (X (X p1)), (F (OR (G p0) (G (NOT p0)))), (F (OR (G p1) (G (NOT p1))))]
False Knowledge obtained : []
Knowledge based reduction with 7 factoid took 155 ms. Reduced automaton from 3 states, 6 edges and 2 AP (stutter insensitive) to 3 states, 6 edges and 2 AP (stutter insensitive).
Stuttering acceptance computed with spot in 104 ms :[(OR (NOT p0) (NOT p1)), (NOT p0), (NOT p1)]

Computed a total of 357 stabilizing places and 988 stable transitions
Detected a total of 357/1189 stabilizing places and 988/2621 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/1 atomic propositions.
Knowledge obtained : [p0, (X p0), (X (X p0)), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 4 factoid took 16 ms. Reduced automaton from 2 states, 2 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
