One deterministic module has affine ranking function (length1 + (-1 * i)) and consists of 5 locations. One deterministic module has affine ranking function (length2 + (-1 * i)) and consists of 5 locations. One deterministic module has affine ranking function null and consists of 5 locations. 2 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 8.1s and 6 iterations.
