One deterministic module has affine ranking function 39 + -2 * c and consists of 4 locations. One deterministic module has affine ranking function length and consists of 2 locations. 4 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 35.0s and 7 iterations. TraceHistogramMax:2. Analysis of lassos took 34.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 13 StatesRemovedByMinimization, 4 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 [2, 0, 0, 0, 0].
