Stuttering acceptance computed with spot in 151 ms :[(OR (AND (NOT p0) (NOT p1)) (AND (NOT p0) (NOT p2))), (NOT p2), true, (OR (AND (NOT p0) (NOT p1)) (AND (NOT p0) (NOT p2)))]
Running random walk in product with property : MedleyA-PT-03-LTLCardinality-15
Product exploration explored 100000 steps with 50000 reset in 156 ms.
Product exploration explored 100000 steps with 50000 reset in 247 ms.
Computed a total of 94 stabilizing places and 87 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 94 transition count 87
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 (NOT p1) (NOT p2)), (X (NOT (AND (NOT p0) p1))), (X (NOT (AND (NOT p0) (NOT p1)))), (X p0), (X (NOT p1)), (X (X (NOT p2))), (F (OR (G p0) (G (NOT p0)))), (F (G (NOT p1))), (F (OR (G p2) (G (NOT p2))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 9 factoid took 18 ms. Reduced automaton from 4 states, 5 edges and 3 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
