### (7) 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.

MUL0(C(z0, z1), z2) → c(ADD0(mul0(z1, z2), z2), MUL0(z1, z2))
We considered the (Usable) Rules:none

MUL0(C(z0, z1), z2) → c(ADD0(mul0(z1, z2), z2), MUL0(z1, z2))
ADD0(C(z0, z1), z2) → c2(ADD0(z1, C(S, z2)))

Polynomial interpretation :

POL(ADD0(x1, x2)) = [4]
POL(C(x1, x2)) = [5] + x2
POL(MUL0(x1, x2)) = [2]x1
