One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 2 locations. One deterministic module has affine ranking function (length2 + ((long long) -1 * i)) and consists of 2 locations. One deterministic module has affine ranking function null and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 18 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.6s and 6 iterations.
