TraceHistogramMax:2. Analysis of lassos took 6.5s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 9 StatesRemovedByMinimization, 3 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 [3, 0, 0, 0, 0].
