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

Termination of R to be shown.

Dependency Pair Analysis



R contains the following Dependency Pairs:

F(x, h(y)) -> F(h(x), y)

Furthermore, R contains one SCC.

DPs
       →DP Problem 1
Argument Filtering and Ordering


Dependency Pair:

F(x, h(y)) -> F(h(x), y)


Rules:


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





The following dependency pair can be strictly oriented:

F(x, h(y)) -> F(h(x), y)


There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
trivial

resulting in one new DP problem.
Used Argument Filtering System:
F(x1, x2) -> x2
h(x1) -> h(x1)

Dependency Graph


Dependency Pair:


Rules:


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





Using the Dependency Graph resulted in no new DP problems.
