One deterministic module has affine ranking function (((long long) -2 * splverifierCounter) + 7) and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.4s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 5.0s. Construction of modules took 0.1s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 6. Automata minimization 0.2s AutomataMinimizationTime, 6 MinimizatonAttempts, 3216 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.1s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [4, 0, 0, 0, 0].
