One deterministic module has affine ranking function unknown-#length-unknown[array] + 8 * j and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.1s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 4.7s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 16 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 17 states and ocurred in iteration 2. Nontrivial modules had stage [2, 0, 0, 0, 0].
