One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function (19 + (-2 * i)) and consists of 4 locations. One deterministic module has affine ranking function ((-2 * i) + 17) and consists of 3 locations. 7 modules have a trivial ranking function, the largest among these consists of 13 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 73.6s and 11 iterations.
