R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
A(b(x)) -> A(x)
Furthermore, R contains one SCC.
R
↳DPs
→DP Problem 1
↳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)
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: A(x1) -> A(x1)
b(x1) -> b(x1)

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