One deterministic module has affine ranking function -2 * i + 9 and consists of 5 locations. One deterministic module has affine ranking function -1 * i + n and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 2.5s and 3 iterations.
