(7) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

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

MAP#2(plus_x(z0), Cons(z1, z2)) → c3(PLUS_X#1(z0, z1), MAP#2(plus_x(z0), z2))
We considered the (Usable) Rules:none
And the Tuples:

PLUS_X#1(S(z0), z1) → c1(PLUS_X#1(z0, z1))
MAP#2(plus_x(z0), Cons(z1, z2)) → c3(PLUS_X#1(z0, z1), MAP#2(plus_x(z0), z2))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(Cons(x1, x2)) = [4] + x2   
POL(MAP#2(x1, x2)) = [2]x2   
POL(PLUS_X#1(x1, x2)) = [2]   
POL(S(x1)) = 0
