One deterministic module has affine ranking function y and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.9s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 1.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 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].
