Computed a total of 231 stabilizing places and 205 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 231 transition count 205
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) p0), (X (NOT (AND (NOT p1) (NOT p0)))), (X (NOT (AND p1 (NOT p0)))), (X (X (NOT (AND (NOT p1) (NOT p0))))), (X (X (NOT (AND p1 (NOT p0))))), (F (G (NOT p1))), (F (G p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 7 factoid took 17 ms. Reduced automaton from 2 states, 4 edges and 2 AP (stutter insensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
