One deterministic module has affine ranking function (((long long) -1 * i) + len) and consists of 3 locations. One deterministic module has affine ranking function (((long long) 2 * j) + 1) and consists of 2 locations. 5 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.0s and 8 iterations. TraceHistogramMax:2. Analysis of lassos took 5.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.5s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 5. Automata minimization 0.0s AutomataMinimizationTime, 6 MinimizatonAttempts, 26 StatesRemovedByMinimization, 6 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, 0, 0, 0].
