Product exploration explored 100000 steps with 50000 reset in 142 ms.
Computed a total of 31 stabilizing places and 40 stable transitions
Computed a total of 31 stabilizing places and 40 stable transitions
Detected a total of 31/222 stabilizing places and 40/310 transitions leading to convergence knowledge of the form 'F(Gp|G!p)' for 1/2 atomic propositions.
Knowledge obtained : [(AND p0 p1), (X (NOT (AND p0 (NOT p1)))), (X (NOT (AND (NOT p0) (NOT p1)))), (X p1), (X (X (NOT (AND p0 (NOT p1))))), (X (X (NOT (AND (NOT p0) (NOT p1))))), (X (X p1)), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : [(X p0), (X (NOT p0)), (X (X p0)), (X (X (NOT p0)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 8 factoid took 12 ms. Reduced automaton from 4 states, 7 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
