The remainder module has 95 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 128.8s and 2 iterations. TraceHistogramMax:1. Analysis of lassos took 128.4s. Construction of modules took 0.1s. Büchi inclusion checks took 0.1s. 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.
