   R
Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

Polynomial Ordering


Dependency Pair:

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


Rules:


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


Strategy:

innermost




The following dependency pair can be strictly oriented:

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


There are no usable rules for innermost that need to be oriented.

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

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rules:


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


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
