The remainder module has 4410 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.9s and 15 iterations. TraceHistogramMax:2. Analysis of lassos took 4.6s. Construction of modules took 0.3s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 0. Minimization of det autom 14. Minimization of nondet autom 0. Automata minimization 0.2s AutomataMinimizationTime, 14 MinimizatonAttempts, 4013 StatesRemovedByMinimization, 8 NontrivialMinimizations. Non-live state removal took 0.2s Buchi closure took 0.0s. Biggest automaton had 4410 states and ocurred in iteration 14. Nontrivial modules had stage [0, 0, 0, 0, 0].
