One deterministic module has affine ranking function -1 * s + length and consists of 5 locations. One deterministic module has affine ranking function -1 * d + unknown-#length-unknown[__builtin_alloca (n * sizeof(char))] and consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.8s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 10.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 6.8ms AutomataMinimizationTime, 1 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 13 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
