One deterministic module has affine ranking function ((-1 * i) + (4611686018427387903 * Alen)) and consists of 5 locations. One deterministic module has affine ranking function (l2 + (-1 * j)) and consists of 4 locations. One nondeterministic module has affine ranking function (l2 + (-1 * j)) and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 14.6s and 7 iterations. TraceHistogramMax:2. Analysis of lassos took 13.5s. Construction of modules took 0.0s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 2. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 10 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 [2, 0, 1, 0, 0].
