One deterministic module has affine ranking function -2 * e + 253 and consists of 4 locations. One deterministic module has affine ranking function 2 * e + 255 and consists of 3 locations. One deterministic module has affine ranking function -2 * e + 253 and consists of 3 locations. One deterministic module has affine ranking function -2 * e + 253 and consists of 3 locations. One deterministic module has affine ranking function 2 * e + 255 and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.2s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 4.0s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 0.1s AutomataMinimizationTime, 5 MinimizatonAttempts, 66 StatesRemovedByMinimization, 4 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 [5, 0, 0, 0, 0].
