Term Rewriting System R:
[y, x]
+(0, y) -> y
+(s(x), 0) -> s(x)
+(s(x), s(y)) -> s(+(s(x), +(y, 0)))
Innermost Termination of R to be shown.
R
↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
+(0, y) -> y
+(s(x), 0) -> s(x)
where the Polynomial interpretation:
| POL(0) | = 0 |
| POL(s(x1)) | = 2 + x1 |
| POL(+(x1, x2)) | = 1 + x1 + 2·x2 |
was used.
Not all Rules of R can be deleted, so we still have to regard a part of R.

↳Dependency Pair Analysis
R contains no Dependency Pairs and therefore no SCCs.
