One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function length2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[nondetString2] and consists of 4 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 5 locations. One deterministic module has affine ranking function 3 * n + 6442450939 * s and consists of 15 locations. One deterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[nondetString2] and consists of 5 locations. One nondeterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[s] and consists of 6 locations. 13 modules have a trivial ranking function, the largest among these consists of 43 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 142.5s and 21 iterations.
