One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. One deterministic module has affine ranking function z and consists of 4 locations. One nondeterministic module has affine ranking function (199 + ((long long) -2 * x)) and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.4s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 1.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 12 StatesRemovedByMinimization, 2 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].
