R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(X) -> G(X)
G(s(X)) -> G(X)
SEL(s(X), cons(Y, Z)) -> SEL(X, activate(Z))
SEL(s(X), cons(Y, Z)) -> ACTIVATE(Z)
ACTIVATE(n_{f}(X)) -> F(X)
Furthermore, R contains two SCCs.

Dependency Pair:
G(s(X)) -> G(X)
Rules:
f(X) -> cons(X, n_{f}(g(X)))
f(X) -> n_{f}(X)
g(0) -> s(0)
g(s(X)) -> s(s(g(X)))
sel(0, cons(X, Y)) -> X
sel(s(X), cons(Y, Z)) -> sel(X, activate(Z))
activate(n_{f}(X)) -> f(X)
activate(X) -> X
We number the DPs as follows:
- G(s(X)) -> G(X)
and get the following Size-Change Graph(s):
which lead(s) to this/these maximal multigraph(s):
D_{P}: empty set
Oriented Rules: none
We used the order Homeomorphic Embedding Order with Non-Strict Precedence.
trivial
with Argument Filtering System:
s(x_{1}) -> s(x_{1})
We obtain no new DP problems.
