Dependency Pair Analysis



R contains the following Dependency Pairs:

A(b(x)) -> A(x)

Furthermore, R contains one SCC.

DPs
       →DP Problem 1
Argument Filtering and Ordering


Dependency Pair:

A(b(x)) -> A(x)


Rule:


a(b(x)) -> b(b(a(x)))





The following dependency pair can be strictly oriented:

A(b(x)) -> A(x)


The following rule can be oriented:

a(b(x)) -> b(b(a(x)))


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

resulting in one new DP problem.
Used Argument Filtering System:
A(x1) -> A(x1)
b(x1) -> b(x1)
a(x1) -> a(x1)

Dependency Graph


Dependency Pair:


Rule:


a(b(x)) -> b(b(a(x)))





Using the Dependency Graph resulted in no new DP problems.
