One deterministic module has affine ranking function null and consists of 2 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 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.9s and 5 iterations.
