One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function null and consists of 3 locations. One nondeterministic module has affine ranking function null and consists of 3 locations. 3 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.8s and 7 iterations.
