One deterministic module has affine ranking function \old(y2) and consists of 7 locations. One deterministic module has affine ranking function \old(y1) and consists of 7 locations. One deterministic module has affine ranking function \old(m) and consists of 10 locations. One deterministic module has affine ranking function \old(m) and consists of 11 locations. One deterministic module has affine ranking function \old(m) and consists of 11 locations. One deterministic module has affine ranking function \old(m) and consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.5s and 7 iterations. TraceHistogramMax:3. Analysis of lassos took 6.6s. Construction of modules took 0.2s. Büchi inclusion checks took 2.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 5. Automata minimization 0.1s AutomataMinimizationTime, 5 MinimizatonAttempts, 61 StatesRemovedByMinimization, 5 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 [6, 0, 0, 0, 0].
