One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.8s and 6 iterations.
