Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 19 StatesRemovedByMinimization, 3 NontrivialMinimizations. 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 [2, 0, 0, 0, 0].
