One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function length2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * d and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 18 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.9s and 7 iterations. TraceHistogramMax:2. Analysis of lassos took 7.0s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 6. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 5 MinimizatonAttempts, 30 StatesRemovedByMinimization, 3 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].
