One deterministic module has affine ranking function cleanupTimeShifts + -1 * i and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.3s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.6s. Construction of modules took 0.5s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 359.1ms AutomataMinimizationTime, 2 MinimizatonAttempts, 8596 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.5s Buchi closure took 0.0s. Biggest automaton had 4838 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
