Term Rewriting System R:
[x, y, z]
+(*(x, y), *(a, y)) -> *(+(x, a), y)
*(*(x, y), z) -> *(x, *(y, z))
Innermost Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
+'(*(x, y), *(a, y)) -> *'(+(x, a), y)
+'(*(x, y), *(a, y)) -> +'(x, a)
*'(*(x, y), z) -> *'(x, *(y, z))
*'(*(x, y), z) -> *'(y, z)
Furthermore, R contains one SCC.

↳DPs
→DP Problem 1
↳Polynomial Ordering
Dependency Pair:
*'(*(x, y), z) -> *'(y, z)
Rules:
+(*(x, y), *(a, y)) -> *(+(x, a), y)
*(*(x, y), z) -> *(x, *(y, z))
Strategy:
innermost
The following dependency pair can be strictly oriented:
*'(*(x, y), z) -> *'(y, z)
There are no usable rules for innermost that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(*'(x1, x2)) | = x1 |
| POL(*(x1, x2)) | = 1 + x2 |
resulting in one new DP problem.

↳Dependency Graph
Dependency Pair:
Rules:
+(*(x, y), *(a, y)) -> *(+(x, a), y)
*(*(x, y), z) -> *(x, *(y, z))
Strategy:
innermost
Using the Dependency Graph resulted in no new DP problems.
