One deterministic module has affine ranking function ((-1 * i) + in_len) and consists of 5 locations. One deterministic module has affine ranking function (out_len + (-1 * i)) and consists of 5 locations. One deterministic module has affine ranking function null and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.0s and 6 iterations.
