One deterministic module has affine ranking function (((long long) -2 * splverifierCounter) + 7) and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.0s and 8 iterations. TraceHistogramMax:1. Analysis of lassos took 6.2s. Construction of modules took 0.3s. Büchi inclusion checks took 2.9s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 13. Automata minimization 1.0s AutomataMinimizationTime, 13 MinimizatonAttempts, 13724 StatesRemovedByMinimization, 5 NontrivialMinimizations. Non-live state removal took 0.7s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [7, 0, 0, 0, 0].
