One deterministic module has affine ranking function -1 * i + cleanupTimeShifts and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 69.7s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 12.1s. Construction of modules took 25.2s. Büchi inclusion checks took 30.3s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 3.1s AutomataMinimizationTime, 1 MinimizatonAttempts, 202926 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 4.2s Buchi closure took 0.2s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [1, 0, 0, 0, 0].
