One deterministic module has affine ranking function -2 * n + 211 and consists of 4 locations. One deterministic module has affine ranking function -2 * n + 211 and consists of 3 locations. One deterministic module has affine ranking function -2 * n + 201 and consists of 4 locations. One nondeterministic module has affine ranking function -2 * n + 211 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 -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 n and consists of 14 locations. One nondeterministic module has affine ranking function c and consists of 8 locations. 5 modules have a trivial ranking function, the largest among these consists of 20 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.8s and 11 iterations.
