Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.


   R
DPs
       →DP Problem 1
Polynomial 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)


There are no usable rules w.r.t. to the implicit AFS that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(b(x1))=  1 + x1  
  POL(A(x1))=  x1  

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rule:


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





Using the Dependency Graph resulted in no new DP problems.
