One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function (19 + ((long long) -2 * i)) and consists of 4 locations. One deterministic module has affine ranking function (len + ((long long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function null and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 21 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 521.7s and 12 iterations.
