By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We used the non-termination processor [17] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

The TRS P consists of the following rules:

HAMMINGLIST3
HAMMINGLIST2
HAMMINGLIST1
LIST3HAMMING
LIST2HAMMING
LIST1HAMMING

The TRS R consists of the following rules:none


s = LIST3 evaluates to t =LIST3

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:




Rewriting sequence

LIST3HAMMING
with rule LIST3HAMMING at position [] and matcher [ ]

HAMMINGLIST3
with rule HAMMINGLIST3

Now applying the matcher to the start term leads to a term which is equal to the last term in the rewriting sequence


All these steps are and every following step will be a correct step w.r.t to Q.
