One deterministic module has affine ranking function -1 * i + length and consists of 5 locations. One deterministic module has 2-nested ranking function (if 8 * unknown-#memory_int-unknown[arr][arr] + unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] > 0 then 1 else 0), (if 8 * unknown-#memory_int-unknown[arr][arr] + unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] > 0 then 8 * unknown-#memory_int-unknown[arr][arr] + unknown-#length-unknown[__builtin_alloca(length*sizeof(int))] else -8 * j + 8 * length) and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.2s and 4 iterations.
