Term Rewriting System R:
[x, y]
f(x, y) -> g(x, y)
g(h(x), y) -> h(f(x, y))
g(h(x), y) -> h(g(x, y))
Termination of R to be shown.

↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(x, y) -> G(x, y)
G(h(x), y) -> F(x, y)
G(h(x), y) -> G(x, y)
Furthermore, R contains one SCC.

↳Polynomial Ordering
Dependency Pairs:
G(h(x), y) -> G(x, y)
G(h(x), y) -> F(x, y)
F(x, y) -> G(x, y)
Rules:
f(x, y) -> g(x, y)
g(h(x), y) -> h(f(x, y))
g(h(x), y) -> h(g(x, y))
The following dependency pairs can be strictly oriented:
G(h(x), y) -> G(x, y)
G(h(x), y) -> F(x, y)
There are no usable rules w.r.t. to the implicit AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(G(x1, x2)) | = x1 |
| POL(h(x1)) | = 1 + x1 |
| POL(F(x1, x2)) | = x1 |
resulting in one new DP problem.

↳Dependency Graph
Dependency Pair:
F(x, y) -> G(x, y)
Rules:
f(x, y) -> g(x, y)
g(h(x), y) -> h(f(x, y))
g(h(x), y) -> h(g(x, y))
Using the Dependency Graph resulted in no new DP problems.
