One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function x and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function x and consists of 5 locations. One deterministic module has affine ranking function x and consists of 5 locations. One nondeterministic module has affine ranking function y and consists of 4 locations. One nondeterministic module has affine ranking function y and consists of 4 locations. One nondeterministic module has affine ranking function x and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.4s and 11 iterations. TraceHistogramMax:4. Analysis of lassos took 4.5s. Construction of modules took 0.2s. Büchi inclusion checks took 1.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 9. Automata minimization 0.1s AutomataMinimizationTime, 9 MinimizatonAttempts, 206 StatesRemovedByMinimization, 9 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 [7, 0, 3, 0, 0].
