Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 9 MinimizatonAttempts, 30 StatesRemovedByMinimization, 6 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 [5, 0, 1, 0, 0].
