One deterministic module has affine ranking function -1 * i + -1 * nondetString1 + unknown-#length-unknown[nondetString1] 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 * sc1 + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[nondetString2] and consists of 5 locations. One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] and consists of 5 locations. 5 modules have a trivial ranking function, the largest among these consists of 21 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.4s and 11 iterations.
