One deterministic module has affine ranking function null and consists of 2 locations. One deterministic module has affine ranking function (9 + ((long long) -2 * i)) and consists of 2 locations. One deterministic module has affine ranking function null and consists of 2 locations. 7 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 25.9s and 11 iterations.
