One deterministic module has affine ranking function null and consists of 4 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 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 6.5s and 4 iterations.
