One deterministic module has affine ranking function (length2 + ((long long) -1 * i)) and consists of 4 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 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.7s and 5 iterations.
