Construction of modules took 0.2s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 0. Minimization of det autom 1. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 45 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 90 states and ocurred in iteration 1. Nontrivial modules had stage [0, 0, 0, 0, 0].
