Term Rewriting System R:
[x, y, z]
f(0, 1, x) -> f(x, x, x)
f(x, y, z) -> 2
0 -> 2
1 -> 2
Innermost Termination of R to be shown.
R
↳Removing Redundant Rules for Innermost Termination
Removing the following rules from R which left hand sides contain non normal subterms
f(0, 1, x) -> f(x, x, x)

↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
f(x, y, z) -> 2
where the Polynomial interpretation:
| POL(0) | = 0 |
| POL(1) | = 0 |
| POL(2) | = 0 |
| POL(f(x1, x2, x3)) | = 1 + x1 + x2 + x3 |
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:
1 -> 2
where the Polynomial interpretation:

| POL(1) | = 1 |
| POL(2) | = 0 |
was used.
