One deterministic module has affine ranking function (((long long) -2 * splverifierCounter) + 7) and consists of 3 locations. 8 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.8s and 9 iterations. TraceHistogramMax:1. Analysis of lassos took 6.7s. Construction of modules took 0.3s. Büchi inclusion checks took 4.6s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 13. Automata minimization 1.7s AutomataMinimizationTime, 13 MinimizatonAttempts, 18607 StatesRemovedByMinimization, 5 NontrivialMinimizations. Non-live state removal took 1.6s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [7, 0, 0, 0, 0].
