Complete graph has no SCC; deadlocks are unavoidable. place count 1003 transition count 952
Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge (and all enablings converge to false).

Knowledge obtained : [(NOT p0), (F (G p0))]
False Knowledge obtained : [(X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 15 ms. Reduced automaton from 3 states, 3 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).

Running random walk in product with property : HirschbergSinclair-PT-45-LTLCardinality-14
Product exploration explored 100000 steps with 50000 reset in 435 ms.
Product exploration explored 100000 steps with 50000 reset in 447 ms.
Computed a total of 1008 stabilizing places and 956 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 1008 transition count 956
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)...)
Starting Z3 with timeout 6000.0 s and query timeout 600000.0 ms
Knowledge obtained : [(AND p1 p0), (X p1), (X p0), (X (X p1)), (F (OR (G p1) (G (NOT p1)))), (F (G p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 6 factoid took 18 ms. Reduced automaton from 4 states, 5 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
