Computed a total of 6 stabilizing places and 5 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 6 transition count 5
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, (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 :(F (G p0))
Knowledge based reduction with 2 factoid took 195 ms. Reduced automaton from 2 states, 3 edges and 1 AP to 1 states, 0 edges and 0 AP.
