One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. One nondeterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.9s and 7 iterations.
