The remainder module has 693 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 139.2s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 138.4s. Construction of modules took 0.4s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 0. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 1163 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 693 states and ocurred in iteration 3. Nontrivial modules had stage [0, 0, 0, 0, 0].
