One deterministic module has affine ranking function 23 + -2 * i2 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.3s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 6.6s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 35.3ms AutomataMinimizationTime, 3 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 156 states and ocurred in iteration 3. Nontrivial modules had stage [1, 0, 0, 0, 0].
