One deterministic module has affine ranking function length1 + -1 * i and consists of 6 locations. One deterministic module has affine ranking function -1 * i + length2 and consists of 4 locations. One deterministic module has affine ranking function 3 * n + -1 * s and consists of 9 locations. One deterministic module has affine ranking function 4 * \old(n) + -1 * s and consists of 11 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * s and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.2s and 9 iterations.
