Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge (and all enablings converge to false).
Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge : F ( (Ga|G!a) & (Gb|G!b)...)
Knowledge obtained : [p0, (X p0), (X (X p0)), (F (G p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(F (G p0))
Knowledge based reduction with 4 factoid took 230 ms. Reduced automaton from 1 states, 2 edges and 1 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
