TraceHistogramMax:3. Analysis of lassos took 8.2s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 6. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 8 MinimizatonAttempts, 13 StatesRemovedByMinimization, 5 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, 1, 0, 0].
