One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 8 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 5 locations. 6 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 13.9s and 11 iterations.
