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[y][y] and consists of 7 locations. One deterministic module has affine ranking function unknown-#memory_int-unknown[x][x] and consists of 4 locations. One deterministic module has 2-phase ranking function (if unknown-#memory_int-unknown[z][z] > 0 then 1 else 0), (if unknown-#memory_int-unknown[z][z] > 0 then unknown-#memory_int-unknown[z][z] else (if aux-*x > 0 && *y > 0 && *z > 0-aux then 1 else 0)) and consists of 5 locations.
