One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function (8589934589 + ((long long) -2 * i)) and consists of 5 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 10 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 16 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 4 modules have a trivial ranking function, the largest among these consists of 25 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.4s and 12 iterations.
