TraceHistogramMax:1. Analysis of lassos took 8.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. Highest rank in rank-based complementation 0. Minimization of det autom 0. Minimization of nondet autom 0. Automata minimization No data available. 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 [0, 0, 0, 0, 0].
