One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function (8589934589 + ((long long) -2 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 11.1s and 7 iterations.
