One deterministic module has affine ranking function -8 * i + 9 * unknown-#length-unknown[x] and consists of 5 locations. One deterministic module has affine ranking function 9 + -2 * i and consists of 4 locations. One deterministic module has affine ranking function -2 * i + 7 and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.2s and 11 iterations. TraceHistogramMax:5. Analysis of lassos took 17.7s. Construction of modules took 0.4s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 10. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 9 MinimizatonAttempts, 41 StatesRemovedByMinimization, 4 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [3, 0, 0, 0, 0].
