One deterministic module has affine ranking function 2 * N + -1 * i2 and consists of 2 locations. One nondeterministic module has affine ranking function 2 * N + -1 * i2 and consists of 2 locations. One nondeterministic module has affine ranking function 2 * N + -1 * i1 and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.4s and 16 iterations. TraceHistogramMax:2. Analysis of lassos took 13.5s. Construction of modules took 0.4s. Büchi inclusion checks took 1.5s. Highest rank in rank-based complementation 3. Minimization of det autom 9. Minimization of nondet autom 7. Automata minimization 0.1s AutomataMinimizationTime, 15 MinimizatonAttempts, 258 StatesRemovedByMinimization, 14 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 [12, 1, 1, 1, 0].
