Proved the following rewrite lemma:

Induction Base:
encArg(gen_if:true:false:filter:nil:cons:cons_app2_0(0))

Induction Step:
encArg(gen_if:true:false:filter:nil:cons:cons_app2_0(+(n60_0, 1))) ->_R^Omega(0)
app(encArg(if), encArg(gen_if:true:false:filter:nil:cons:cons_app2_0(n60_0))) ->_R^Omega(0)
app(if, encArg(gen_if:true:false:filter:nil:cons:cons_app2_0(n60_0))) ->_IH
app(if, *3_0)

We have rt in Omega(1) and sz in O(n). Thus, we have irc_R in Omega(n^0).

(23) 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:

   encArg_1
   encode_app_2
   encode_if
   encode_true
   encode_false
   encode_filter
   encode_nil
   encode_cons
   app_2

Due to the following rules being added:

   encArg(v0) -> null_encArg [0]
   encode_app(v0, v1) -> null_encode_app [0]
   encode_if -> null_encode_if [0]
   encode_true -> null_encode_true [0]
   encode_false -> null_encode_false [0]
   encode_filter -> null_encode_filter [0]
   encode_nil -> null_encode_nil [0]
   encode_cons -> null_encode_cons [0]
   app(v0, v1) -> null_app [0]

And the following fresh constants:    null_encArg, null_encode_app, null_encode_if, null_encode_true, null_encode_false, null_encode_filter, null_encode_nil, null_encode_cons, null_app

The TRS is a completely defined constructor system, as every type has a constant constructor and the following rules were added:

   encArg(v0) -> null_encArg [0]
   encode_app(v0, v1) -> null_encode_app [0]
   encode_if -> null_encode_if [0]
   encode_true -> null_encode_true [0]
   encode_false -> null_encode_false [0]
   encode_filter -> null_encode_filter [0]
   encode_nil -> null_encode_nil [0]
   encode_cons -> null_encode_cons [0]
   app(v0, v1) -> null_app [0]

And the following fresh constants:    null_encArg, null_encode_app, null_encode_if, null_encode_true, null_encode_false, null_encode_filter, null_encode_nil, null_encode_cons, null_app
