One deterministic module has affine ranking function unknown-#length-unknown[s] + -1 * s and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (out_len)] + -1 * s and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.6s and 5 iterations. TraceHistogramMax:1. Analysis of lassos took 8.0s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 1. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 3 MinimizatonAttempts, 17 StatesRemovedByMinimization, 3 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].
