Product exploration explored 100000 steps with 33333 reset in 106 ms.
Computed a total of 75 stabilizing places and 56 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 75 transition count 56
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 p1 (NOT p0)), (X (X (NOT (AND (NOT p1) p0)))), (X (X (NOT (AND (NOT p1) (NOT p0))))), (F (OR (G p1) (G (NOT p1)))), (F (OR (G p0) (G (NOT p0))))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge :(X (X (NOT (AND (NOT p1) (NOT p0)))))
Knowledge based reduction with 5 factoid took 95 ms. Reduced automaton from 5 states, 8 edges and 2 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
