R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(g(X)) -> F(X)
Furthermore, R contains one SCC.
R
↳DPs
→DP Problem 1
↳Forward Instantiation Transformation
Dependency Pair:
F(g(X)) -> F(X)
Rule:
f(g(X)) -> f(X)
Strategy:
innermost
On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule
F(g(X)) -> F(X)
one new Dependency Pair
is created:
F(g(g(X''))) -> F(g(X''))
The transformation is resulting in one new DP problem:

↳DPs
→DP Problem 1
↳FwdInst
→DP Problem 2
↳Forward Instantiation Transformation
Dependency Pair:
F(g(g(X''))) -> F(g(X''))
Rule:
f(g(X)) -> f(X)
Strategy:
innermost
On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule
F(g(g(X''))) -> F(g(X''))
one new Dependency Pair
is created:
F(g(g(g(X'''')))) -> F(g(g(X'''')))
The transformation is resulting in one new DP problem:
R
↳DPs
→DP Problem 1
↳FwdInst
→DP Problem 2
↳FwdInst
...
→DP Problem 3
↳Polynomial Ordering
Dependency Pair:
F(g(g(g(X'''')))) -> F(g(g(X'''')))
Rule:
f(g(X)) -> f(X)
Strategy:
innermost
The following dependency pair can be strictly oriented:
F(g(g(g(X'''')))) -> F(g(g(X'''')))
There are no usable rules for innermost that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(g(x1)) | = 1 + x1 |
| POL(F(x1)) | = 1 + x1 |
resulting in one new DP problem.

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