One deterministic module has affine ranking function -1 * i + cleanupTimeShifts and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.2s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.6s. Construction of modules took 0.4s. Büchi inclusion checks took 1.3s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 194.7ms AutomataMinimizationTime, 2 MinimizatonAttempts, 6854 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.2s Buchi closure took 0.0s. Biggest automaton had 3608 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
