TraceHistogramMax:3. Analysis of lassos took 10.8s. Construction of modules took 0.3s. Büchi inclusion checks took 1.9s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 28 StatesRemovedByMinimization, 4 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 [2, 0, 1, 0, 0].
