One deterministic module has affine ranking function (((long) -1 * i) + n) and consists of 4 locations. One deterministic module has affine ranking function (((long) -2 * i) + 1) and consists of 14 locations. One deterministic module has affine ranking function null and consists of 10 locations. One deterministic module has affine ranking function (size + ((long) -1 * i)) and consists of 6 locations. One nondeterministic module has affine ranking function j and consists of 7 locations. 6 modules have a trivial ranking function, the largest among these consists of 18 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 16.1s and 12 iterations.
