One deterministic module has affine ranking function (((long long) 2 * e) + 255) and consists of 3 locations. One deterministic module has affine ranking function (((long long) -2 * e) + 253) 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 2.7s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 2.1s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 4. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 50 StatesRemovedByMinimization, 3 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].
