One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 5 locations. One deterministic module has affine ranking function null and consists of 7 locations. One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.8s and 8 iterations.
