One deterministic module has affine ranking function -2 * op2 + 1 and consists of 5 locations. One deterministic module has affine ranking function -2 * op6 + 1 and consists of 4 locations. One deterministic module has affine ranking function -2 * op3 + 1 and consists of 4 locations. One deterministic module has affine ranking function 1 + -2 * op8 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. One deterministic module has affine ranking function -2 * splverifierCounter + 7 and consists of 4 locations. 6 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.3s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 8.6s. Construction of modules took 0.2s. Büchi inclusion checks took 4.0s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 10. Automata minimization 1.0s AutomataMinimizationTime, 10 MinimizatonAttempts, 17405 StatesRemovedByMinimization, 9 NontrivialMinimizations. Non-live state removal took 0.8s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [6, 0, 0, 0, 0].
