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. One nondeterministic module has affine ranking function null and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.3s and 6 iterations.
