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

↳Argument Filtering and Ordering
Dependency Pair:
F(g(x, y), f(y, y)) -> F(g(y, x), y)
Rule:
f(g(x, y), f(y, y)) -> f(g(y, x), y)
The following dependency pair can be strictly oriented:
F(g(x, y), f(y, y)) -> F(g(y, x), y)
There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
POL(g(x1, x2)) | = 1 + x1 + x2 |
POL(F(x1, x2)) | = 1 + x1 + x2 |
POL(f(x1, x2)) | = 1 + x1 + x2 |
resulting in one new DP problem.
Used Argument Filtering System: F(x1, x2) -> F(x1, x2)
g(x1, x2) -> g(x1, x2)
f(x1, x2) -> f(x1, x2)

Dependency Pair:
Rule:
f(g(x, y), f(y, y)) -> f(g(y, x), y)
Using the Dependency Graph resulted in no new DP problems.
