One deterministic module has affine ranking function (array_size + ((long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function j and consists of 5 locations. One nondeterministic module has affine ranking function j and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.7s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 5.6s. Construction of modules took 0.1s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 11 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 [2, 0, 1, 0, 0].
