(55) CdtRuleRemovalProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

ISNEPAL(mark(z0)) → c18(ISNEPAL(z0))

We considered the (Usable) Rules:none
And the Tuples:

__'(mark(z0), z1) → c11(__'(z0, z1))
