Product exploration explored 100000 steps with 23268 reset in 102 ms.
Computed a total of 9 stabilizing places and 9 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 9 transition count 9
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 p1) (NOT p0)), (X (NOT (AND p1 (NOT p0)))), (X (X (NOT (AND p1 (NOT p0))))), (F (G (NOT p1))), (F (G p0))]
False Knowledge obtained : [(X (AND (NOT p1) (NOT p0))), (X (NOT (AND (NOT p1) (NOT p0)))), (X (X (AND (NOT p1) (NOT p0)))), (X (X (NOT (AND (NOT p1) (NOT p0)))))]
Property proved to be true thanks to knowledge :(F (G p0))
Knowledge based reduction with 5 factoid took 394 ms. Reduced automaton from 2 states, 4 edges and 2 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
