One deterministic module has affine ranking function -2 * i + unknown-#length-unknown[__builtin_alloca (array_size * sizeof(int))] and consists of 4 locations. One deterministic module has affine ranking function array_size + -1 * j and consists of 4 locations. One nondeterministic module has affine ranking function 4 * array_size + -1 * min and consists of 15 locations. One nondeterministic module has affine ranking function array_size + -1 * j and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 17 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.5s and 9 iterations. TraceHistogramMax:3. Analysis of lassos took 5.4s. Construction of modules took 0.2s. Büchi inclusion checks took 1.7s. Highest rank in rank-based complementation 3. Minimization of det autom 3.
