[2023-03-12 11:27:39] [INFO ] Dead Transitions using invariants and state equation in 282 ms found 0 transitions.
Starting structural reductions in LTL mode, iteration 1 : 18/21 places, 18/20 transitions.
Finished structural reductions in LTL mode , in 1 iterations and 493 ms. Remains : 18/21 places, 18/20 transitions.
Stuttering acceptance computed with spot in 150 ms :[(NOT p0), (NOT p0)]
Running random walk in product with property : AirplaneLD-COL-0100-LTLCardinality-12 automaton TGBA Formula[mat=[[{ cond=true, acceptance={} source=0 dest: 1}], [{ cond=(NOT p0), acceptance={0} source=1 dest: 1}]], initial=0, aps=[p0:(LEQ s0 s8)], 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][false, false]]
Product exploration explored 100000 steps with 21129 reset in 298 ms.
Product exploration explored 100000 steps with 21025 reset in 155 ms.
Computed a total of 18 stabilizing places and 18 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 18 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 : [(NOT p0), (F (G p0))]
False Knowledge obtained : [(X (NOT p0)), (X p0), (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 158 ms. Reduced automaton from 2 states, 2 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
