One deterministic module has affine ranking function \old(n) and consists of 4 locations. One deterministic module has affine ranking function -1 * n and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.8s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 9.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 11 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 18 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
