Minimization of nondet autom 15. Automata minimization 0.3s AutomataMinimizationTime, 15 MinimizatonAttempts, 9813 StatesRemovedByMinimization, 13 NontrivialMinimizations. Non-live state removal took 0.7s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [2, 1, 3, 0, 5].
