Term Rewriting System R:
[x]
f(s(x)) -> s(s(f(p(s(x)))))
f(0) -> 0
p(s(x)) -> x
Termination of R to be shown.

↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(s(x)) -> F(p(s(x)))
F(s(x)) -> P(s(x))
Furthermore, R contains one SCC.
R
↳DPs
→DP Problem 1
↳Narrowing Transformation
Dependency Pair:
F(s(x)) -> F(p(s(x)))
Rules:
f(s(x)) -> s(s(f(p(s(x)))))
f(0) -> 0
p(s(x)) -> x
On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule
F(s(x)) -> F(p(s(x)))
one new Dependency Pair
is created:
F(s(x'')) -> F(x'')
The transformation is resulting in one new DP problem:
R
↳DPs
→DP Problem 1
↳Nar
→DP Problem 2
↳Remaining Obligation(s)
The following remains to be proven:
Dependency Pair:
F(s(x'')) -> F(x'')
Rules:
f(s(x)) -> s(s(f(p(s(x)))))
f(0) -> 0
p(s(x)) -> x
Termination of R could not be shown.
