   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)
*'(x, *(minus(y), y)) -> *'(y, y)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Polynomial Ordering


Dependency Pairs:

*'(x, *(minus(y), y)) -> *'(y, y)
*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)


Rule:


*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)





The following dependency pair can be strictly oriented:

*'(x, *(minus(y), y)) -> *'(y, y)


Additionally, the following rule can be oriented:

*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(*'(x1, x2))=  1 + x1 + x2  
  POL(*(x1, x2))=  x1 + x2  
  POL(minus(x1))=  1 + x1  

resulting in one new DP problem.

           →DP Problem 2
             ↳Polynomial Ordering


Dependency Pair:

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)


Rule:


*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)





The following dependency pair can be strictly oriented:

*'(x, *(minus(y), y)) -> *'(minus(*(y, y)), x)


Additionally, the following rule can be oriented:

*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(*'(x1, x2))=  x1 + x2  
  POL(*(x1, x2))=  1  
  POL(minus(x1))=  0  

resulting in one new DP problem.

Dependency Pair:


Rule:


*(x, *(minus(y), y)) -> *(minus(*(y, y)), x)





Using the Dependency Graph resulted in no new DP problems.
