One deterministic module has affine ranking function (((long) -1 * j) + l) and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.1s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 4.9s. Construction of modules took 0.0s. Büchi inclusion checks took 0.1s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 1 MinimizatonAttempts, 3 StatesRemovedByMinimization, 1 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].
