TraceHistogramMax:2. Analysis of lassos took 6.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 18 StatesRemovedByMinimization, 2 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, 1, 0, 0].
