One deterministic module has affine ranking function (211 + ((long) -2 * n)) and consists of 4 locations. One deterministic module has affine ranking function (211 + ((long) -2 * n)) and consists of 3 locations. One deterministic module has affine ranking function (((long) -2 * n) + 201) and consists of 4 locations. One nondeterministic module has affine ranking function (211 + ((long) -2 * n)) and consists of 3 locations. One nondeterministic module has affine ranking function c and consists of 3 locations. One nondeterministic module has affine ranking function (((long) -2 * n) + 221) and consists of 4 locations. One nondeterministic module has affine ranking function n and consists of 7 locations. One nondeterministic module has affine ranking function c and consists of 9 locations. 5 modules have a trivial ranking function, the largest among these consists of 6 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.4s and 10 iterations.
