One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 4 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[y][y] and consists of 5 locations.
