Starting structural reductions in LTL mode, iteration 1 : 19/20 places, 18/20 transitions.
Finished structural reductions, in 1 iterations. Remains : 19/20 places, 18/20 transitions.
Stuttering acceptance computed with spot in 128 ms :[(NOT p0), (NOT p0), (NOT p0)]
Running random walk in product with property : AirplaneLD-COL-0020-LTLFireability-15 automaton TGBA Formula[mat=[[{ cond=(NOT p0), acceptance={0} source=0 dest: 0}], [{ cond=true, acceptance={} source=1 dest: 0}], [{ cond=true, acceptance={} source=2 dest: 1}]], initial=2, aps=[p0:(OR (LT s9 1) (LT s13 1))], nbAcceptance=1, properties=[trans-labels, explicit-labels, trans-acc, deterministic, no-univ-branch, unambiguous, semi-deterministic, stutter-sensitive, very-weak, weak, inherently-weak], stateDesc=[null, null, null][false, false, false]]
Product exploration explored 100000 steps with 27857 reset in 104 ms.
Product exploration explored 100000 steps with 27897 reset in 113 ms.
Computed a total of 19 stabilizing places and 18 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 19 transition count 18
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 : [p0, (F (G p0))]
False Knowledge obtained : [(X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge :(F (G p0))
Knowledge based reduction with 2 factoid took 101 ms. Reduced automaton from 3 states, 3 edges and 1 AP to 1 states, 0 edges and 0 AP.
FORMULA AirplaneLD-COL-0020-LTLFireability-15 TRUE TECHNIQUES KNOWLEDGE
Treatment of property AirplaneLD-COL-0020-LTLFireability-15 finished in 637 ms.
All properties solved by simple procedures.
Total runtime 12237 ms.
