One deterministic module has affine ranking function -2 * z + 207 and consists of 10 locations. One deterministic module has affine ranking function -2 * y + 207 and consists of 10 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 21.8s and 5 iterations.
