Term Rewriting System R:
[x, y, z]
*(x, *(y, z)) -> *(*(x, y), z)
*(x, x) -> x

Innermost Termination of R to be shown. 



   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.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and 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 w.r.t. to the AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(*'(x1, x2))=  x1 + x2  
  POL(*(x1, x2))=  1 + x1 + x2  

resulting in one new DP problem.
Used Argument Filtering System:
*'(x1, x2) -> *'(x1, x2)
*(x1, x2) -> *(x1, x2)

Dependency Pair:


Rules:


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


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
