*(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.

`         ↳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 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.
