One deterministic module has affine ranking function (k + ((long long) -1 * z)) and consists of 4 locations. One deterministic module has affine ranking function (k + ((long long) -1 * z)) and consists of 4 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function y and consists of 5 locations. One deterministic module has affine ranking function (((long long) 2 * x) + 1) and consists of 5 locations. One deterministic module has affine ranking function x and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.6s and 8 iterations. TraceHistogramMax:1. Analysis of lassos took 7.4s. Construction of modules took 0.1s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 12 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 [6, 0, 0, 0, 0].
