↳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)
Rule:
a(b(x)) -> b(b(a(x)))
Strategy:
innermost
The following dependency pair can be strictly oriented:
A(b(x)) -> A(x)
There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: A(x1) -> A(x1)
b(x1) -> b(x1)

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