One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 7 locations. One deterministic module has affine ranking function null and consists of 10 locations. One deterministic module has affine ranking function null and consists of 8 locations. 4 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.6s and 9 iterations.
