One deterministic module has affine ranking function x and consists of 4 locations. One deterministic module has affine ranking function y and consists of 4 locations. One deterministic module has affine ranking function z and consists of 4 locations. One deterministic module has affine ranking function x and consists of 3 locations. One nondeterministic module has affine ranking function z and consists of 4 locations.
