One deterministic module has affine ranking function -2 * i + 199999 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.3s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 3.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 2 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].
