The remainder module has 302 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 4.9s. Construction of modules took 0.1s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 0. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 2 MinimizatonAttempts, 405 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 302 states and ocurred in iteration 2. Nontrivial modules had stage [0, 0, 0, 0, 0].
