One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] + -1 * x and consists of 4 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] and consists of 5 locations. One deterministic module has affine ranking function 3 + -2 * i and consists of 10 locations. One deterministic module has affine ranking function -1 * i + N and consists of 3 locations. 9 modules have a trivial ranking function, the largest among these consists of 24 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 54.7s and 15 iterations. TraceHistogramMax:3. Analysis of lassos took 50.2s. Construction of modules took 1.7s. Büchi inclusion checks took 2.5s. Highest rank in rank-based complementation 3. Minimization of det autom 14. Minimization of nondet autom 0. Automata minimization 0.1s AutomataMinimizationTime, 13 MinimizatonAttempts, 203 StatesRemovedByMinimization, 10 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 [5, 0, 0, 0, 0].
