One deterministic module has affine ranking function n and consists of 4 locations. One deterministic module has affine ranking function c and consists of 3 locations. One deterministic module has affine ranking function -2 * n + 211 and consists of 3 locations. One deterministic module has affine ranking function n and consists of 5 locations. One nondeterministic module has affine ranking function c and consists of 3 locations. One nondeterministic module has affine ranking function -2 * n + 211 and consists of 3 locations. One nondeterministic module has affine ranking function -2 * n + 201 and consists of 5 locations. One nondeterministic module has affine ranking function n and consists of 5 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 9 locations. One nondeterministic module has affine ranking function n and consists of 11 locations. One nondeterministic module has affine ranking function n and consists of 13 locations. One nondeterministic module has affine ranking function c and consists of 6 locations. 4 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 19.8s and 15 iterations.
