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 :(X p0)
Knowledge based reduction with 4 factoid took 80 ms. Reduced automaton from 2 states, 2 edges and 1 AP to 1 states, 0 edges and 0 AP.
