TraceHistogramMax:1. Analysis of lassos took 6.6s. Construction of modules took 0.3s. Büchi inclusion checks took 3.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 13. Automata minimization 1.1s AutomataMinimizationTime, 13 MinimizatonAttempts, 14213 StatesRemovedByMinimization, 5 NontrivialMinimizations. Non-live state removal took 0.7s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [7, 0, 0, 0, 0].
