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))
Innermost 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.

↳Argument Filtering and 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))
Strategy:
innermost
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 for innermost that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: G(x1, x2) -> x1
h(x1) -> h(x1)
F(x1, x2) -> x1

↳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))
Strategy:
innermost
Using the Dependency Graph resulted in no new DP problems.
Innermost Termination of R successfully shown.
