One deterministic module has affine ranking function (((long long) -1 * i) + MAX) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function (((long long) -2 * i) + 1) and consists of 8 locations. One deterministic module has affine ranking function null and consists of 13 locations. One deterministic module has affine ranking function null and consists of 4 locations. 4 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 20.0s and 10 iterations.
