↳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)
Strategy:
innermost
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 for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: F(x1, x2) -> F(x1, x2)
g(x1, x2) -> g
f(x1, x2) -> f(x1, x2)

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