The remainder module has 636 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 5.0s. Construction of modules took 0.2s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 0. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 3 MinimizatonAttempts, 650 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [0, 0, 0, 0, 0].
