Computed a total of 144 stabilizing places and 625 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 144 transition count 625
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 : [(NOT p0), (F (G p0))]
False Knowledge obtained : [(X (NOT p0)), (X p0), (X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 16 ms. Reduced automaton from 2 states, 3 edges and 1 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
