Minimization of nondet autom 6. Automata minimization 0.1s AutomataMinimizationTime, 7 MinimizatonAttempts, 93 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 [2, 0, 0, 0, 0].
