Term Rewriting System R:
[x]
g(s(x)) -> f(x)
g(0) -> 0
f(0) -> s(0)
f(s(x)) -> s(s(g(x)))

Termination of R to be shown.

Dependency Pair Analysis



R contains the following Dependency Pairs:

G(s(x)) -> F(x)
F(s(x)) -> G(x)

Furthermore, R contains one SCC.

       →DP Problem 1
Argument Filtering and Ordering


Dependency Pairs:

F(s(x)) -> G(x)
G(s(x)) -> F(x)


Rules:


g(s(x)) -> f(x)
g(0) -> 0
f(0) -> s(0)
f(s(x)) -> s(s(g(x)))





The following dependency pairs can be strictly oriented:

F(s(x)) -> G(x)
G(s(x)) -> F(x)


There are no usable rules w.r.t. to the AFS that need to be oriented.
Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
{G, s} > F

resulting in one new DP problem.
Used Argument Filtering System:
F(x1) -> F(x1)
G(x1) -> G(x1)
s(x1) -> s(x1)

Dependency Graph


Dependency Pair:


Rules:


g(s(x)) -> f(x)
g(0) -> 0
f(0) -> s(0)
f(s(x)) -> s(s(g(x)))





Using the Dependency Graph resulted in no new DP problems.
