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 17.9s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.5s. Construction of modules took 0.6s. Büchi inclusion checks took 4.9s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 2.3s AutomataMinimizationTime, 2 MinimizatonAttempts, 206 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 1.7s Buchi closure took 0.1s. Biggest automaton had 33309 states and ocurred in iteration 2. Nontrivial modules had stage [1, 0, 0, 0, 0].
