   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

*'(x, *(y, z)) -> *'(otimes(x, y), z)
*'(+(x, y), z) -> *'(x, z)
*'(+(x, y), z) -> *'(y, z)
*'(x, oplus(y, z)) -> *'(x, y)
*'(x, oplus(y, z)) -> *'(x, z)

Furthermore, R contains one SCC.

       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pairs:

*'(x, oplus(y, z)) -> *'(x, z)
*'(+(x, y), z) -> *'(y, z)
*'(+(x, y), z) -> *'(x, z)
*'(x, oplus(y, z)) -> *'(x, y)
*'(x, *(y, z)) -> *'(otimes(x, y), z)


Rules:


*(x, *(y, z)) -> *(otimes(x, y), z)
*(1, y) -> y
*(+(x, y), z) -> oplus(*(x, z), *(y, z))
*(x, oplus(y, z)) -> oplus(*(x, y), *(x, z))





The following dependency pairs can be strictly oriented:

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


There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(*'(x1, x2))=  x1 + x2  
  POL(otimes(x1, x2))=  x1 + x2  
  POL(*(x1, x2))=  x1 + x2  
  POL(oplus(x1, x2))=  1 + x1 + x2  
  POL(+(x1, x2))=  x1 + x2  

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

Dependency Pairs:

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


Rules:


*(x, *(y, z)) -> *(otimes(x, y), z)
*(1, y) -> y
*(+(x, y), z) -> oplus(*(x, z), *(y, z))
*(x, oplus(y, z)) -> oplus(*(x, y), *(x, z))





Using the Dependency Graph the DP problem was split into 2 DP problems.
