Graph (complete) has 2487 edges and 235 vertex of which 234 are kept as prefixes of interest. Removing 1 places using SCC suffix rule.2 ms
Computed a total of 116 stabilizing places and 669 stable transitions
Detected a total of 116/235 stabilizing places and 669/907 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/1 atomic propositions.
Knowledge obtained : [(NOT 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 14 ms. Reduced automaton from 2 states, 2 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
