One deterministic module has affine ranking function length + -1 * k and consists of 5 locations. One deterministic module has affine ranking function -1 * a + unknown-#length-unknown[arr] and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.6s and 5 iterations. TraceHistogramMax:2. Analysis of lassos took 5.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 15.7ms AutomataMinimizationTime, 3 MinimizatonAttempts, 3 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 12 states and ocurred in iteration 3. Nontrivial modules had stage [2, 0, 0, 0, 0].
