Product exploration explored 100000 steps with 23802 reset in 136 ms.
Computed a total of 21 stabilizing places and 18 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 21 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 : [(AND (NOT p0) p1), (X (X (NOT (AND (NOT p0) (NOT p1))))), (F (G (NOT p0))), (F (G p1))]
False Knowledge obtained : [(X (X (NOT p0))), (X (X p0))]
Property proved to be true thanks to knowledge :(F (G p1))
Knowledge based reduction with 4 factoid took 161 ms. Reduced automaton from 4 states, 5 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
