One deterministic module has affine ranking function ((-1 * i) + len) and consists of 4 locations. One deterministic module has affine ranking function ((-2 * i) + 1) and consists of 7 locations. One deterministic module has affine ranking function (len + (-1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 15 locations. One deterministic module has affine ranking function (len + (-1 * i)) and consists of 3 locations. One deterministic module has affine ranking function ((2 * j) + 1) and consists of 3 locations. 9 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 26.2s and 16 iterations.
