Term Rewriting System R:
[X, Y]
zeros -> cons(0, zeros)
incr(cons(X, Y)) -> cons(s(X), incr(Y))
hd(cons(X, Y)) -> X
tl(cons(X, Y)) -> Y

Termination of R to be shown.

`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

NATS -> ZEROS
ZEROS -> ZEROS
INCR(cons(X, Y)) -> INCR(Y)

Furthermore, R contains three SCCs.

`     ↳DPs`
`       →DP Problem 1`
`         ↳Argument Filtering and Ordering`
`       →DP Problem 2`
`         ↳Remaining`
`       →DP Problem 3`
`         ↳Remaining`

Dependency Pair:

INCR(cons(X, Y)) -> INCR(Y)

Rules:

zeros -> cons(0, zeros)
incr(cons(X, Y)) -> cons(s(X), incr(Y))
hd(cons(X, Y)) -> X
tl(cons(X, Y)) -> Y

The following dependency pair can be strictly oriented:

INCR(cons(X, Y)) -> INCR(Y)

There are no usable rules w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System:
INCR(x1) -> INCR(x1)
cons(x1, x2) -> cons(x1, x2)

`       →DP Problem 3`
`         ↳Remaining`

Dependency Pair:

Rules:

zeros -> cons(0, zeros)
incr(cons(X, Y)) -> cons(s(X), incr(Y))
hd(cons(X, Y)) -> X
tl(cons(X, Y)) -> Y

Using the Dependency Graph resulted in no new DP problems.

The following remains to be proven:
• Dependency Pair:

ZEROS -> ZEROS

Rules:

zeros -> cons(0, zeros)
incr(cons(X, Y)) -> cons(s(X), incr(Y))
hd(cons(X, Y)) -> X
tl(cons(X, Y)) -> Y

• Dependency Pair:

Rules:

zeros -> cons(0, zeros)
incr(cons(X, Y)) -> cons(s(X), incr(Y))
hd(cons(X, Y)) -> X
tl(cons(X, Y)) -> Y
