The TRS R consists of the following rules:

   d(b(x1)) -> c(c(x1))
   b(c(x1)) -> b(a(c(x1)))

(19) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)))
Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.
   D(z0) -> c12(C(z0))
   D(b(z0)) -> c6(C(c(z0)))
   D(b(z0)) -> c6(C(z0))
We considered the (Usable) Rules:none
And the Tuples:
   ENCARG(a(z0)) -> c1(ENCARG(z0))
   ENCARG(cons_c(z0)) -> c2(C(encArg(z0)), ENCARG(z0))
   ENCARG(cons_d(z0)) -> c3(D(encArg(z0)), ENCARG(z0))
   C(z0) -> c10
   ENCARG(cons_b(z0)) -> c4(ENCARG(z0))
   D(z0) -> c12(C(z0))
   ENCODE_C(z0) -> c6(C(encArg(z0)))
   ENCODE_D(z0) -> c6(D(encArg(z0)))
   D(b(z0)) -> c6(C(c(z0)))
   D(b(z0)) -> c6(C(z0))
The order we found is given by the following interpretation:

Polynomial interpretation :

   POL(C(x_1)) = 0
   POL(D(x_1)) = [1]
   POL(ENCARG(x_1)) = x_1
   POL(ENCODE_C(x_1)) = 0

   POL(c12(x_1)) = x_1

   POL(c4(x_1)) = x_1
   POL(c6(x_1)) = x_1
