One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.3s and 4 iterations.
