One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function (((long long) 2 * i) + 1) and consists of 5 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 3 locations. One nondeterministic module has affine ranking function (((long long) 2 * i) + 1) and consists of 5 locations. 6 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.2s and 12 iterations.
