The remainder module has 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.6s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 7.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 2 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 14 states and ocurred in iteration 3. Nontrivial modules had stage [1, 0, 0, 0, 0].
