One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 3 locations. One deterministic module has affine ranking function (\old(size) + ((long) -1 * \old(startIndex))) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function (size + ((long) -1 * index)) and consists of 4 locations. One nondeterministic module has affine ranking function null and consists of 6 locations. 5 modules have a trivial ranking function, the largest among these consists of 17 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.7s and 11 iterations.
