One deterministic module has affine ranking function 9 * unknown-#length-unknown[x] + -8 * i and consists of 5 locations. One deterministic module has affine ranking function -2 * i + 9 and consists of 4 locations. One deterministic module has affine ranking function -16 * i + 7 * unknown-#length-unknown[x] and consists of 4 locations. 11 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.5s and 15 iterations. TraceHistogramMax:5. Analysis of lassos took 13.2s. Construction of modules took 0.3s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 14. Minimization of nondet autom 0. Automata minimization 45.3ms AutomataMinimizationTime, 13 MinimizatonAttempts, 85 StatesRemovedByMinimization, 9 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 67 states and ocurred in iteration 12. Nontrivial modules had stage [3, 0, 0, 0, 0].
