One deterministic module has affine ranking function (((long long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function k and consists of 6 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 1.9s and 3 iterations.
