One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.8s and 4 iterations.
