One deterministic module has affine ranking function -1 * v + -4 * j + unknown-#length-unknown[v] and consists of 5 locations. One deterministic module has affine ranking function -2 * j + unknown-#length-unknown[v] and consists of 7 locations. One deterministic module has affine ranking function -4 * k + unknown-#length-unknown[v] and consists of 4 locations. One nondeterministic module has affine ranking function 2 * i + 1 and consists of 5 locations. 8 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 21.3s and 13 iterations. TraceHistogramMax:3. Analysis of lassos took 18.6s. Construction of modules took 0.7s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 7. Automata minimization 0.1s AutomataMinimizationTime, 11 MinimizatonAttempts, 113 StatesRemovedByMinimization, 8 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, 1, 0, 0].
