↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(s(0)) -> F(p(s(0)))
F(s(0)) -> P(s(0))
ACTIVATE(nf(X)) -> F(X)
Furthermore, R contains one SCC.
R
↳DPs
→DP Problem 1
↳Narrowing Transformation
Dependency Pair:
F(s(0)) -> F(p(s(0)))
Rules:
f(0) -> cons(0, nf(s(0)))
f(s(0)) -> f(p(s(0)))
f(X) -> nf(X)
p(s(0)) -> 0
activate(nf(X)) -> f(X)
activate(X) -> X
On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule
F(s(0)) -> F(p(s(0)))
one new Dependency Pair
is created:
F(s(0)) -> F(0)
The transformation is resulting in no new DP problems.
Termination of R successfully shown.
