Term Rewriting System R:
[x, y, z]
*(i(x), x) -> 1
*(1, y) -> y
*(x, 0) -> 0
*(*(x, y), z) -> *(x, *(y, z))
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) -> *'(y, z)
Furthermore, R contains one SCC.

↳DPs
→DP Problem 1
↳Polynomial Ordering
Dependency Pairs:
*'(*(x, y), z) -> *'(y, z)
*'(*(x, y), z) -> *'(x, *(y, z))
Rules:
*(i(x), x) -> 1
*(1, y) -> y
*(x, 0) -> 0
*(*(x, y), z) -> *(x, *(y, z))
The following dependency pairs can be strictly oriented:
*'(*(x, y), z) -> *'(y, z)
*'(*(x, y), z) -> *'(x, *(y, z))
There are no usable rules w.r.t. to the implicit AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
POL(i(x1)) | = 0 |
POL(0) | = 0 |
POL(*'(x1, x2)) | = x1 |
POL(1) | = 0 |
POL(*(x1, x2)) | = 1 + x1 + x2 |
resulting in one new DP problem.

↳Dependency Graph
Dependency Pair:
Rules:
*(i(x), x) -> 1
*(1, y) -> y
*(x, 0) -> 0
*(*(x, y), z) -> *(x, *(y, z))
Using the Dependency Graph resulted in no new DP problems.
