(7) CdtRuleRemovalProof (UPPER BOUND(ADD(n^2)) transformation)

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

F(z0, h(z1)) → c1(F(h(z0), z1))
We considered the (Usable) Rules:none
And the Tuples:

F(z0, h(z1)) → c1(F(h(z0), z1))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(F(x1, x2)) = [2]x22   
POL(c1(x1)) = x1   
POL(h(x1)) = [2] + x1
