One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function (((long long) -2 * i) + 199999) and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.8s and 4 iterations.
