One deterministic module has affine ranking function len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * i + len and consists of 4 locations. One deterministic module has affine ranking function -1 * i + len and consists of 3 locations. One deterministic module has affine ranking function j + 2 * i and consists of 10 locations. 9 modules have a trivial ranking function, the largest among these consists of 10 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.1s and 14 iterations.
