One nondeterministic module has affine ranking function 2 * an + -2 * i + 1 and consists of 5 locations. One nondeterministic module has affine ranking function 2 * bn + -2 * j + 1 and consists of 6 locations. One nondeterministic module has affine ranking function -2 * j + 2 * bn + 1 and consists of 5 locations. One nondeterministic module has affine ranking function -1 * j + bn and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.0s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 2.9s. Construction of modules took 0.2s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 2 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 21 states and ocurred in iteration 1. Nontrivial modules had stage [4, 0, 0, 0, 0].
