One deterministic module has affine ranking function i and consists of 9 locations. One deterministic module has affine ranking function 2 * unknown-#memory_int-unknown[p][p] + 1 and consists of 5 locations. One deterministic module has affine ranking function aux-rec(op)-aux + i and consists of 8 locations. One deterministic module has affine ranking function i and consists of 8 locations.
