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.

↳Argument Filtering and 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))
The following usable rules w.r.t. to the AFS can be oriented:
*(i(x), x) -> 1
*(1, y) -> y
*(x, 0) -> 0
*(*(x, y), z) -> *(x, *(y, z))
Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
{*', *, 1}
resulting in one new DP problem.
Used Argument Filtering System: *'(x1, x2) -> *'(x1, x2)
*(x1, x2) -> *(x1, x2)
i(x1) -> i(x1)

↳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.
