The remainder module has 1660 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.4s and 15 iterations. TraceHistogramMax:4. Analysis of lassos took 9.4s. Construction of modules took 2.0s. Büchi inclusion checks took 2.1s. Highest rank in rank-based complementation 3. Minimization of det autom 11. Minimization of nondet autom 3. Automata minimization 0.2s AutomataMinimizationTime, 14 MinimizatonAttempts, 1184 StatesRemovedByMinimization, 8 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had 1730 states and ocurred in iteration 12. Nontrivial modules had stage [1, 0, 0, 0, 0].
