One deterministic module has affine ranking function -1 * z + 100 and consists of 10 locations. One deterministic module has affine ranking function -1 * y + 100 and consists of 9 locations. 2 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.0s and 5 iterations.
