Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 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].
