Term Rewriting System R:
[X]
a -> g(c)
g(a) -> b
f(g(X), b) -> f(a, X)
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
g(a) -> b

↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
a -> g(c)
where the Polynomial interpretation:
| POL(c) | = 0 |
| POL(g(x1)) | = x1 |
| POL(b) | = 1 |
| POL(a) | = 1 |
| POL(f(x1, x2)) | = x1 + 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.
