R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
A(b(x)) -> A(x)
Furthermore, R contains one SCC.

↳Argument Filtering and Ordering
Dependency Pair:
A(b(x)) -> A(x)
Rules:
a(b(x)) -> b(a(x))
a(c(x)) -> x
The following dependency pair can be strictly oriented:
A(b(x)) -> A(x)
The following rules can be oriented:
a(b(x)) -> b(a(x))
a(c(x)) -> x
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(c(x1)) | = x1 |
| POL(b(x1)) | = 1 + x1 |
| POL(a(x1)) | = x1 |
| POL(A(x1)) | = x1 |
resulting in one new DP problem.
Used Argument Filtering System: A(x1) -> A(x1)
b(x1) -> b(x1)
a(x1) -> a(x1)
c(x1) -> c(x1)

Dependency Pair:
Rules:
a(b(x)) -> b(a(x))
a(c(x)) -> x
Using the Dependency Graph resulted in no new DP problems.
