`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

MINUS(s(x), s(y)) -> MINUS(x, y)
QUOT(s(x), s(y)) -> QUOT(minus(x, y), s(y))
QUOT(s(x), s(y)) -> MINUS(x, y)
APP(add(n, x), y) -> APP(x, y)
CONCAT(cons(u, v), y) -> CONCAT(v, y)
LESSLEAVES(cons(u, v), cons(w, z)) -> LESSLEAVES(concat(u, v), concat(w, z))
LESSLEAVES(cons(u, v), cons(w, z)) -> CONCAT(u, v)
LESSLEAVES(cons(u, v), cons(w, z)) -> CONCAT(w, z)

Furthermore, R contains seven SCCs.

Dependency Pair:

Rules:

minus(x, 0) -> x
minus(s(x), s(y)) -> minus(x, y)
quot(0, s(y)) -> 0
quot(s(x), s(y)) -> s(quot(minus(x, y), s(y)))
app(nil, y) -> y
reverse(nil) -> nil
shuffle(nil) -> nil
concat(leaf, y) -> y
concat(cons(u, v), y) -> cons(u, concat(v, y))
lessleaves(x, leaf) -> false
lessleaves(leaf, cons(w, z)) -> true
lessleaves(cons(u, v), cons(w, z)) -> lessleaves(concat(u, v), concat(w, z))

Using the Dependency Graph resulted in no new DP problems.

Dependency Pair:

Rules:

minus(x, 0) -> x
minus(s(x), s(y)) -> minus(x, y)
quot(0, s(y)) -> 0
quot(s(x), s(y)) -> s(quot(minus(x, y), s(y)))

The following dependency pair can be strictly oriented:

Additionally, the following rules can be oriented:

minus(x, 0) -> x
minus(s(x), s(y)) -> minus(x, y)
quot(0, s(y)) -> 0
quot(s(x), s(y)) -> s(quot(minus(x, y), s(y)))
app(nil, y) -> y
reverse(nil) -> nil
shuffle(nil) -> nil
concat(leaf, y) -> y
concat(cons(u, v), y) -> cons(u, concat(v, y))
lessleaves(x, leaf) -> false
lessleaves(leaf, cons(w, z)) -> true
lessleaves(cons(u, v), cons(w, z)) -> lessleaves(concat(u, v), concat(w, z))

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(false) =  0 POL(SHUFFLE(x1)) =  x1 POL(minus(x1, x2)) =  x1 POL(true) =  0 POL(less_leaves(x1, x2)) =  0 POL(add(x1, x2)) =  1 + x2 POL(reverse(x1)) =  x1 POL(shuffle(x1)) =  x1 POL(0) =  0 POL(cons(x1, x2)) =  0 POL(quot(x1, x2)) =  0 POL(nil) =  0 POL(s(x1)) =  x1 POL(leaf) =  0 POL(app(x1, x2)) =  x1 + x2 POL(concat(x1, x2)) =  x2

resulting in one new DP problem.
