Obligation:
Runtime Complexity Weighted TRS with Types.
The TRS R consists of the following rules:

   b -> c [1]
   encArg(a) -> a [0]
   encArg(c) -> c [0]

encode_c :: a:c:cons_f:cons_b

Rewrite Strategy: INNERMOST
----------------------------------------

(9) CompletionProof (UPPER BOUND(ID))
The transformation into a RNTS is sound, since:

(a) The obligation is a constructor system where every type has a constant constructor,

(b) The following defined symbols do not have to be completely defined, as they can never occur inside other defined symbols:
none

(c) The following functions are completely defined:

   b
   f_2
   encArg_1
   encode_f_2
   encode_a
   encode_b
   encode_c

Due to the following rules being added:

   encArg(v0) -> null_encArg [0]
   encode_f(v0, v1) -> null_encode_f [0]
   encode_a -> null_encode_a [0]
   encode_b -> null_encode_b [0]
   encode_c -> null_encode_c [0]
   f(v0, v1) -> null_f [0]

And the following fresh constants:    null_encArg, null_encode_f, null_encode_a, null_encode_b, null_encode_c, null_f
