The remainder module has 84 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.6s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 4.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. Highest rank in rank-based complementation 0. Minimization of det autom 1. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 84 states and ocurred in iteration 1. Nontrivial modules had stage [0, 0, 0, 0, 0].
