One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 6 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 4 modules have a trivial ranking function, the largest among these consists of 16 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.0s and 8 iterations.
