One deterministic module has affine ranking function ((((long long) -2 * q) + ((long long) 2 * n)) + 3) 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 3.1s and 3 iterations.
