One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 9 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 5 modules have a trivial ranking function, the largest among these consists of 39 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.0s and 9 iterations.
