TraceHistogramMax:1. Analysis of lassos took 3.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 14 states and ocurred in iteration 1. Nontrivial modules had stage [1, 0, 0, 0, 0].
