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 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 12.1s and 7 iterations.
