One deterministic module has affine ranking function -1 * str1 + -1 * i + unknown-#length-unknown[str1] and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[str2] + 2 * i and consists of 4 locations. One deterministic module has affine ranking function 2 * j + unknown-#length-unknown[str2] and consists of 5 locations. 6 modules have a trivial ranking function, the largest among these consists of 21 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 20.4s and 10 iterations. TraceHistogramMax:5. Analysis of lassos took 18.9s. Construction of modules took 0.4s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 9. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 8 MinimizatonAttempts, 23 StatesRemovedByMinimization, 5 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 [3, 0, 0, 0, 0].
