Product exploration explored 100000 steps with 10686 reset in 700 ms.
Computed a total of 54 stabilizing places and 100 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 54 transition count 100
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 p0) p1), (F (G p0)), (F (G (NOT p1)))]
False Knowledge obtained : [(X (AND (NOT p0) (NOT p1))), (X (NOT (AND (NOT p0) (NOT p1)))), (X (AND p0 (NOT p1))), (X (NOT (AND p0 (NOT p1)))), (X p0), (X (NOT p0)), (X p1), (X (NOT p1)), (X (X (AND (NOT p0) (NOT p1)))), (X (X (NOT (AND (NOT p0) (NOT p1))))), (X (X (AND p0 (NOT p1)))), (X (X (NOT (AND p0 (NOT p1))))), (X (X p0)), (X (X (NOT p0))), (X (X p1)), (X (X (NOT p1)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 3 factoid took 19 ms. Reduced automaton from 2 states, 4 edges and 2 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
