One deterministic module has affine ranking function (((long) -1 * i) + in_len) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. 1 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 3.6s and 4 iterations.
