One deterministic module has affine ranking function null and consists of 2 locations. One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function j and consists of 4 locations. 8 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 24.2s and 13 iterations.
