The remainder module has 1104 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.5s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 16.1s. Construction of modules took 0.3s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 0. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.2s AutomataMinimizationTime, 5 MinimizatonAttempts, 216 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 1104 states and ocurred in iteration 5. Nontrivial modules had stage [0, 0, 0, 0, 0].
