Term Rewriting System R:
[X]

a_{_g}(X) -> g(X)
a_{_c} -> d
a_{_c} -> c
a_{_h}(d) -> a_{_g}(c)
a_{_h}(X) -> h(X)
mark(g(X)) -> a_{_g}(X)

     ↳Dependency Pair Analysis

R contains the following Dependency Pairs:

A_{_G}(X) -> A_{_H}(X)
A_{_H}(d) -> A_{_G}(c)
MARK(g(X)) -> A_{_G}(X)
MARK(h(X)) -> A_{_H}(X)
MARK(c) -> A_{_C}

Furthermore, R contains one SCC.

         ↳Argument Filtering and Ordering

Dependency Pairs:

A_{_H}(d) -> A_{_G}(c)
A_{_G}(X) -> A_{_H}(X)

Rules:

a_{_g}(X) -> a_{_h}(X)
a_{_g}(X) -> g(X)
a_{_c} -> d
a_{_c} -> c
a_{_h}(d) -> a_{_g}(c)
a_{_h}(X) -> h(X)
mark(g(X)) -> a_{_g}(X)
mark(h(X)) -> a_{_h}(X)
mark(c) -> a_{_c}
mark(d) -> d

The following dependency pairs can be strictly oriented:

A_{_H}(d) -> A_{_G}(c)
A_{_G}(X) -> A_{_H}(X)

The following rules can be oriented:

a_{_g}(X) -> a_{_h}(X)
a_{_g}(X) -> g(X)
a_{_c} -> d
a_{_c} -> c
a_{_h}(d) -> a_{_g}(c)
a_{_h}(X) -> h(X)
mark(g(X)) -> a_{_g}(X)
mark(h(X)) -> a_{_h}(X)
mark(c) -> a_{_c}
mark(d) -> d

Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:

{d, a_{_c}, mark} > A_{_G} > A_{_H}
{d, a_{_c}, mark} > {a_{_g}, a_{_h}} > h
{d, a_{_c}, mark} > {a_{_g}, a_{_h}} > g
{d, a_{_c}, mark} > c

resulting in one new DP problem.
Used Argument Filtering System:

A_{_G}(x₁) -> A_{_G}(x₁)
A_{_H}(x₁) -> A_{_H}(x₁)
a_{_g}(x₁) -> a_{_g}(x₁)
a_{_h}(x₁) -> a_{_h}(x₁)
g(x₁) -> g(x₁)
a_{_c} -> a_{_c}
h(x₁) -> h(x₁)
mark(x₁) -> mark(x₁)

             ↳Dependency Graph

Dependency Pair:

Rules:

a_{_g}(X) -> a_{_h}(X)
a_{_g}(X) -> g(X)
a_{_c} -> d
a_{_c} -> c
a_{_h}(d) -> a_{_g}(c)
a_{_h}(X) -> h(X)
mark(g(X)) -> a_{_g}(X)
mark(h(X)) -> a_{_h}(X)
mark(c) -> a_{_c}
mark(d) -> d

Using the Dependency Graph resulted in no new DP problems.
