One deterministic module has affine ranking function -2 * i + unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] and consists of 7 locations. One deterministic module has affine ranking function -1 * j + length and consists of 3 locations. One nondeterministic module has affine ranking function unknown-#memory_int-unknown[arr][arr + j * 4] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.2s and 6 iterations. TraceHistogramMax:2. Analysis of lassos took 5.0s. Construction of modules took 0.1s. Büchi inclusion checks took 0.8s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 3. Automata minimization 0.0s AutomataMinimizationTime, 4 MinimizatonAttempts, 9 StatesRemovedByMinimization, 3 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had 18 states and ocurred in iteration 3. Nontrivial modules had stage [2, 0, 1, 0, 0].
