Construction of modules took 0.3s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 0. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 4 MinimizatonAttempts, 1461 StatesRemovedByMinimization, 3 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 [0, 0, 0, 0, 0].
