False Knowledge obtained : [(X p0), (X (NOT p0)), (X (X (NOT p1))), (X (X p1)), (X (X p0)), (X (X (NOT p0)))]
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 12 ms. Reduced automaton from 2 states, 3 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
FORMULA RefineWMG-PT-015016-LTLFireability-15 TRUE TECHNIQUES KNOWLEDGE
Treatment of property RefineWMG-PT-015016-LTLFireability-15 finished in 10390 ms.
All properties solved by simple procedures.
Total runtime 101811 ms.
