One deterministic module has affine ranking function -1 * unknown-#memory_int-unknown[x][x] + unknown-#memory_int-unknown[z][z] + unknown-#memory_int-unknown[y][y] and consists of 6 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[z][z] and consists of 6 locations.
