Complete graph has no SCC; deadlocks are unavoidable. place count 20 transition count 22
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 : [(AND (NOT p0) (NOT p1)), (X (NOT p0)), (X (X (NOT p0))), (X (X (NOT p1))), (F (G (NOT p0))), (F (G (NOT p1)))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(F (G (NOT p1)))
Knowledge based reduction with 6 factoid took 249 ms. Reduced automaton from 3 states, 5 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
