Term Rewriting System R:
[x, y]
f(g(x), s(0), y) -> f(y, y, g(x))
g(s(x)) -> s(g(x))
g(0) -> 0
Innermost Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(g(x), s(0), y) -> F(y, y, g(x))
G(s(x)) -> G(x)
Furthermore, R contains one SCC.

↳DPs

↳Argument Filtering and Ordering
Dependency Pair:
G(s(x)) -> G(x)
Rules:
f(g(x), s(0), y) -> f(y, y, g(x))
g(s(x)) -> s(g(x))
g(0) -> 0
Strategy:
innermost
The following dependency pair can be strictly oriented:
G(s(x)) -> G(x)
There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
trivial
resulting in one new DP problem.
Used Argument Filtering System: G(x1) -> G(x1)
s(x1) -> s(x1)

Dependency Pair:
Rules:
f(g(x), s(0), y) -> f(y, y, g(x))
g(s(x)) -> s(g(x))
g(0) -> 0
Strategy:
innermost
Using the Dependency Graph resulted in no new DP problems.
