One deterministic module has affine ranking function (((long long) -1 * i) + length) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.5s and 5 iterations.
