One deterministic module has affine ranking function \old(y2) and consists of 6 locations. One deterministic module has affine ranking function y1 and consists of 5 locations. One nondeterministic module has affine ranking function y1 and consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.4s and 4 iterations. TraceHistogramMax:2. Analysis of lassos took 4.6s. Construction of modules took 0.2s. Büchi inclusion checks took 1.3s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 18 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 [2, 0, 1, 0, 0].
