One deterministic module has affine ranking function (255 + ((long) -1 * x)) and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.9s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 0 StatesRemovedByMinimization, 0 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 [1, 0, 0, 0, 0].
