One deterministic module has affine ranking function \old(n) and consists of 4 locations. One deterministic module has affine ranking function -1 * n and consists of 5 locations. One deterministic module has affine ranking function n and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 15.8s and 4 iterations.
