One deterministic module has affine ranking function -2 * i + 199999 and consists of 4 locations. One deterministic module has affine ranking function -2 * i + 199999 and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 5 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 4.2s and 4 iterations.
