Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 7 MinimizatonAttempts, 15 StatesRemovedByMinimization, 5 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 [4, 0, 1, 0, 0].
