(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:

   minus_2
   le_2
   gcd_2
   if_gcd_3
   encArg_1
   encode_le_2
   encode_0
   encode_true
   encode_s_1
   encode_false
   encode_minus_2
   encode_gcd_2
   encode_if_gcd_3

Due to the following rules being added:

   encArg(v0) -> null_encArg [0]
   encode_le(v0, v1) -> null_encode_le [0]
   encode_0 -> null_encode_0 [0]
   encode_true -> null_encode_true [0]
   encode_s(v0) -> null_encode_s [0]
   encode_false -> null_encode_false [0]
   encode_minus(v0, v1) -> null_encode_minus [0]
   encode_gcd(v0, v1) -> null_encode_gcd [0]
   encode_if_gcd(v0, v1, v2) -> null_encode_if_gcd [0]
   minus(v0, v1) -> null_minus [0]
   le(v0, v1) -> null_le [0]
   gcd(v0, v1) -> null_gcd [0]
   if_gcd(v0, v1, v2) -> null_if_gcd [0]

And the following fresh constants:    null_encArg, null_encode_le, null_encode_0, null_encode_true, null_encode_s, null_encode_false, null_encode_minus, null_encode_gcd, null_encode_if_gcd, null_minus, null_le, null_gcd, null_if_gcd
