One deterministic module has affine ranking function 2 * us + 1 and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.2s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 10.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. 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].
