One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function (length2 + ((long long) -1 * i)) and consists of 4 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 nondeterministic module has affine ranking function null and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 28 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.3s and 9 iterations.
