Product exploration explored 100000 steps with 50000 reset in 590 ms.
Computed a total of 236 stabilizing places and 235 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 236 transition count 235
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 p1) p0), (X (NOT (AND (NOT p0) (NOT p1)))), (X p0), (X (NOT p1)), (X (X (NOT p1))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 7 factoid took 21 ms. Reduced automaton from 3 states, 3 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
