Product exploration explored 100000 steps with 14509 reset in 118 ms.
Computed a total of 16 stabilizing places and 16 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 16 transition count 16
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 p0), (X (NOT p0)), (X (X p0)), (X (X (NOT p0)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 18 ms. Reduced automaton from 1 states, 2 edges and 1 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
