One deterministic module has affine ranking function null and consists of 6 locations. 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 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.5s and 6 iterations.
