Term Rewriting System R:
[x, y]
f(g(x, y), f(y, y)) -> f(g(y, x), y)

Termination of R to be shown.

`     ↳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.

`       →DP Problem 1`
`         ↳Polynomial 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)

Additionally, the following rule can be oriented:

f(g(x, y), f(y, y)) -> f(g(y, x), y)

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(g(x1, x2)) =  0 POL(f(x1, x2)) =  1 + x1 POL(F(x1, x2)) =  x2

resulting in one new DP problem.

`             ↳Dependency Graph`

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.
