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 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.5s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 3.5s. Construction of modules took 0.3s. Büchi inclusion checks took 2.0s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.8s AutomataMinimizationTime, 2 MinimizatonAttempts, 206 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.7s Buchi closure took 0.0s. Biggest automaton had 33309 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
