One deterministic module has affine ranking function -2 * i + 9 * unknown-#length-unknown[string_A] and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[string_A] + -1 * nc_A and consists of 4 locations. One deterministic module has affine ranking function -1 * nc_B + unknown-#length-unknown[string_B] and consists of 4 locations. One deterministic module has affine ranking function -2 * i + unknown-#length-unknown[string_A] and consists of 9 locations. One deterministic module has affine ranking function -2 * j + unknown-#length-unknown[string_A] and consists of 8 locations. One deterministic module has affine ranking function -2 * j + unknown-#length-unknown[string_A] and consists of 9 locations. One deterministic module has affine ranking function -1 * i + nc_A and consists of 3 locations. One deterministic module has affine ranking function -4 * i + 3 * nc_A and consists of 8 locations. One deterministic module has affine ranking function unknown-#length-unknown[string_A] + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * i + nc_A and consists of 4 locations. One deterministic module has affine ranking function -2 * i + 2 * j + 5 * unknown-#length-unknown[string_B] and consists of 16 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[string_A] + -6 * j and consists of 11 locations. One nondeterministic module has affine ranking function -1 * i + nc_A and consists of 3 locations. 14 modules have a trivial ranking function, the largest among these consists of 22 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 157.5s and 28 iterations.
