TraceHistogramMax:4. Analysis of lassos took 9.9s. Construction of modules took 0.2s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 6. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 9 MinimizatonAttempts, 50 StatesRemovedByMinimization, 7 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 [4, 0, 0, 0, 0].
