One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString2] + -1 * nondetString2 and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * s and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.2s and 6 iterations. TraceHistogramMax:1. Analysis of lassos took 8.2s. Construction of modules took 0.1s. Büchi inclusion checks took 0.6s. Highest rank in rank-based complementation 3. Minimization of det autom 5. Minimization of nondet autom 0. Automata minimization 23.9ms AutomataMinimizationTime, 4 MinimizatonAttempts, 5 StatesRemovedByMinimization, 2 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 30 states and ocurred in iteration 4. Nontrivial modules had stage [3, 0, 0, 0, 0].
