One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.3s and 6 iterations.
