One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (in_len)] + -1 * nptr and consists of 6 locations. 5 modules have a trivial ranking function, the largest among these consists of 28 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.1s and 9 iterations. TraceHistogramMax:2. Analysis of lassos took 9.6s. Construction of modules took 0.4s. Büchi inclusion checks took 0.9s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 5. Automata minimization 0.0s AutomataMinimizationTime, 7 MinimizatonAttempts, 212 StatesRemovedByMinimization, 6 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].
