One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (in_len)] and consists of 6 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (in_len)] and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.9s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 6.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 2. Automata minimization 9.7ms AutomataMinimizationTime, 2 MinimizatonAttempts, 3 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 15 states and ocurred in iteration 1. Nontrivial modules had stage [2, 0, 0, 0, 0].
