One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function (3 + ((long long) -2 * i)) and consists of 8 locations. One deterministic module has affine ranking function (((long long) -1 * i) + N) and consists of 4 locations. One deterministic module has affine ranking function (N + ((long long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function (((long long) -1 * i) + N) and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 24 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.6s and 13 iterations.
