INTLIST19_IN_AA → INTLIST19_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(14) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = INTLIST19_IN_AA evaluates to t =INTLIST19_IN_AA

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

• Semiunifier: [ ]
• Matcher: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from INTLIST19_IN_AA to INTLIST19_IN_AA.

R is empty.

s(x1)  =  s(x1)
.(x1, x2)  =  .(x1, x2)

(19) PiDPToQDPProof (SOUND transformation)

Q DP problem:
The TRS P consists of the following rules:

INTLIST67_IN_AA → INTLIST67_IN_AA

R is empty.
Q is empty.
We have to consider all (P,Q,R)-chains.

(21) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = INTLIST67_IN_AA evaluates to t =INTLIST67_IN_AA

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

• Matcher: [ ]
• Semiunifier: [ ]

---

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from INTLIST67_IN_AA to INTLIST67_IN_AA.

Transforming (infinitary) constructor rewriting Pi-DP problem [LOPSTR] into ordinary QDP problem [LPAR04] by application of Pi.

INT1_IN_GGA(s(s(T67)), s(s(T68))) → INT1_IN_GGA(T67, T68)

(42) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] 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:

• INT1_IN_GGA(s(s(T67)), s(s(T68))) → INT1_IN_GGA(T67, T68)
  The graph contains the following edges 1 > 1, 2 > 2

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by semiunifying a rule from P directly.

s = INTLIST19_IN_AA evaluates to t =INTLIST19_IN_AA

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

• Semiunifier: [ ]
• Matcher: [ ]

The DP semiunifies directly so there is only one rewrite step from INTLIST19_IN_AA to INTLIST19_IN_AA.

We have to consider all (P,Q,R)-chains.

(83) QDPSizeChangeProof (EQUIVALENT transformation)

By using the subterm criterion [SUBTERM_CRITERION] together with the size-change analysis [AAECC05] 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:

• INT1_IN_GGA(s(s(T67)), s(s(T68))) → INT1_IN_GGA(T67, T68)
  The graph contains the following edges 1 > 1, 2 > 2

(84) YES
