One deterministic module has affine ranking function x and consists of 5 locations. One deterministic module has affine ranking function a and consists of 4 locations. One deterministic module has affine ranking function x and consists of 5 locations. One nondeterministic module has affine ranking function x and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.9s and 6 iterations. TraceHistogramMax:3. Analysis of lassos took 2.4s. Construction of modules took 0.1s. Büchi inclusion checks took 1.1s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 45 StatesRemovedByMinimization, 3 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 [3, 0, 1, 0, 0].
