Computed a total of 93 stabilizing places and 105 stable transitions
Complete graph has no SCC; deadlocks are unavoidable. place count 93 transition count 105
Detected that all paths lead to deadlock. Applying this knowledge to assert that all AP eventually converge (and all enablings converge to false).
AF dead knowledge conclusive for 3 formulas.
