One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[nondetString2] + -1 * nondetString2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * s2 and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.6s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 10.2s. Construction of modules took 0.1s. Büchi inclusion checks took 1.0s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 2 StatesRemovedByMinimization, 2 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 [2, 1, 0, 0, 0].
