One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * s and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.4s and 7 iterations. TraceHistogramMax:2. Analysis of lassos took 9.2s. Construction of modules took 0.1s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 1. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 25 StatesRemovedByMinimization, 3 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].
