One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function (n + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 3 locations. 5 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.8s and 10 iterations.
