One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 6 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.3s and 5 iterations.
