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

↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
f(x, h(y)) -> f(h(x), y)
where the Polynomial interpretation:
| POL(h(x1)) | = 1 + x1 |
| POL(f(x1, x2)) | = x1 + 2·x2 |
was used.
All Rules of R can be deleted.

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