TraceHistogramMax:1. Analysis of lassos took 4.5s. Construction of modules took 0.3s. Büchi inclusion checks took 3.4s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 1.6s AutomataMinimizationTime, 2 MinimizatonAttempts, 206 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 1.9s Buchi closure took 0.1s. Biggest automaton had 50769 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
