↳Removing Redundant Rules for Innermost Termination
Removing the following rules from R which left hand sides contain non normal subterms
top(rec(up(x))) -> top(check(rec(x)))
top(sent(up(x))) -> top(check(rec(x)))
top(no(up(x))) -> top(check(rec(x)))

↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
rec(bot) -> up(sent(bot))
where the Polynomial interpretation:
POL(rec(x1)) | = 2·x1 |
POL(no(x1)) | = x1 |
POL(bot) | = 1 |
POL(up(x1)) | = x1 |
POL(check(x1)) | = x1 |
POL(sent(x1)) | = x1 |
was used.
Not all Rules of R can be deleted, so we still have to regard a part of R.
