One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function null and consists of 4 locations. 6 modules have a trivial ranking function, the largest among these consists of 22 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.4s and 10 iterations.
