One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 6 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 5 locations. One nondeterministic module has affine ranking function null and consists of 6 locations.
