TraceHistogramMax:1. Analysis of lassos took 5.8s. Construction of modules took 0.7s. Büchi inclusion checks took 3.3s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 1.7s AutomataMinimizationTime, 2 MinimizatonAttempts, 206 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 2.2s Buchi closure took 0.1s. Biggest automaton had 52389 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
