One deterministic module has affine ranking function (1 + ((long long) -2 * op8)) and consists of 4 locations. 5 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.0s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 8.5s. Construction of modules took 0.4s. Büchi inclusion checks took 3.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 9. Automata minimization 0.5s AutomataMinimizationTime, 9 MinimizatonAttempts, 6465 StatesRemovedByMinimization, 4 NontrivialMinimizations. Non-live state removal took 0.4s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [5, 0, 0, 0, 0].
