One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function ((-1 * j) + length) and consists of 3 locations. One deterministic module has affine ranking function null and consists of 5 locations. One nondeterministic module has affine ranking function null and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.9s and 7 iterations.
