One deterministic module has affine ranking function null and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.0s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 6.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 2 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [3, 0, 0, 0, 0].
