One deterministic module has affine ranking function null and consists of 10 locations. One deterministic module has affine ranking function (((long) 2 * \old(i)) + 1) and consists of 5 locations. One nondeterministic module has affine ranking function (((long) 2 * \old(i)) + 1) and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 24 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.7s and 7 iterations.
