Refiners :[State Equation: 2/2 constraints, PredecessorRefiner: 1/1 constraints, Known Traps: 0/0 constraints]
After SMT, in 93ms problems are : Problem set: 0 solved, 1 unsolved
Search for dead transitions found 0 dead transitions in 93ms
Finished structural reductions in LTL mode , in 1 iterations and 148 ms. Remains : 2/2 places, 2/2 transitions.
Stuttering acceptance computed with spot in 108 ms :[(NOT p0), (NOT p0), true]
Running random walk in product with property : Referendum-COL-0020-LTLFireability-15
Product exploration explored 100000 steps with 50000 reset in 27 ms.
Product exploration explored 100000 steps with 50000 reset in 32 ms.
Computed a total of 2 stabilizing places and 2 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 2 transition count 2
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), (X p0), (F (G (NOT p0)))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 3 factoid took 17 ms. Reduced automaton from 3 states, 3 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
