Computed a total of 5122 stabilizing places and 5123 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 5122 transition count 5123
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 p0 p1), (X (NOT (AND p0 (NOT p1)))), (X p0), true, (X (X p1)), (F (G p0)), (F (G p1))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(F (G p1))
Knowledge based reduction with 7 factoid took 224 ms. Reduced automaton from 5 states, 8 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
