Product exploration explored 100000 steps with 33333 reset in 620 ms.
Computed a total of 3703 stabilizing places and 506 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 3703 transition count 506
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 p1 p0), (X (X (NOT (AND (NOT p1) (NOT p0))))), (X (X p0)), (X (X (NOT (AND (NOT p1) p0)))), (X (X p1)), (F (G p1)), (F (G p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 7 factoid took 19 ms. Reduced automaton from 4 states, 5 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
