One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (n * sizeof(char))] + -1 * d and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.6s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 7.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 4. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 3 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 20 states and ocurred in iteration 2. Nontrivial modules had stage [3, 0, 0, 0, 0].
