The remainder module has 947 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.9s and 19 iterations. TraceHistogramMax:2. Analysis of lassos took 4.5s. Construction of modules took 0.6s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 14. Minimization of nondet autom 5. Automata minimization 0.3s AutomataMinimizationTime, 19 MinimizatonAttempts, 2738 StatesRemovedByMinimization, 13 NontrivialMinimizations. Non-live state removal took 0.2s Buchi closure took 0.0s.
