Complete graph has no SCC; deadlocks are unavoidable. place count 588 transition count 2744
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 p1) (NOT p0)), (F (G p1)), (F (G p0))]
False Knowledge obtained : [(X (NOT p1)), (X p1), (X (NOT p0)), (X p0)]
Property proved to be true thanks to conjunction of knowledge (Minato strategy)
Knowledge based reduction with 3 factoid took 102 ms. Reduced automaton from 3 states, 6 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
