Term Rewriting System R:
[X]
af(X) -> g(h(f(X)))
af(X) -> f(X)
mark(f(X)) -> af(mark(X))
mark(g(X)) -> g(X)
mark(h(X)) -> h(mark(X))
Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
MARK(f(X)) -> AF(mark(X))
MARK(f(X)) -> MARK(X)
MARK(h(X)) -> MARK(X)
Furthermore, R contains one SCC.

↳DPs

↳Argument Filtering and Ordering
Dependency Pairs:
MARK(h(X)) -> MARK(X)
MARK(f(X)) -> MARK(X)
Rules:
af(X) -> g(h(f(X)))
af(X) -> f(X)
mark(f(X)) -> af(mark(X))
mark(g(X)) -> g(X)
mark(h(X)) -> h(mark(X))
The following dependency pairs can be strictly oriented:
MARK(h(X)) -> MARK(X)
MARK(f(X)) -> MARK(X)
There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: MARK(x1) -> MARK(x1)
f(x1) -> f(x1)
h(x1) -> h(x1)

↳Dependency Graph
Dependency Pair:
Rules:
af(X) -> g(h(f(X)))
af(X) -> f(X)
mark(f(X)) -> af(mark(X))
mark(g(X)) -> g(X)
mark(h(X)) -> h(mark(X))
Using the Dependency Graph resulted in no new DP problems.
