     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pair:

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


Rule:


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





The following dependency pair can be strictly oriented:

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


There are no usable rules w.r.t. to the AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(b(x1))=  x1  
  POL(a(x1))=  1 + x1  
  POL(A(x1))=  1 + x1  

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

Dependency Pair:


Rule:


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





Using the Dependency Graph resulted in no new DP problems.
