We use the technique of [LOPSTR]. With regard to the inferred argument filtering the predicates were used in the following modes:
conf1_in: (b)
del6_in: (f,b,f)
del18_in: (f,f,b)
conf19_in: (b) (f)
del229_in: (b,f) (f,f)

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

DEL34_IN_AAA(X261, cons(T82, T84), cons(T82, X262)) → DEL34_IN_AAA(X261, T84, X262)

R is empty.

cons(x1, x2)  =  cons(x2)
DEL34_IN_AAA(x1, x2, x3)  =  DEL34_IN_AAA

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

(12) PiDPToQDPProof (SOUND transformation)

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

(13) Obligation:

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

DEL34_IN_AAADEL34_IN_AAA

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 = DEL34_IN_AAA evaluates to t =DEL34_IN_AAA

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 DEL34_IN_AAA to DEL34_IN_AAA.

(17) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(18) Obligation:

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

DEL43_IN_AAA(X324, cons(X325, X326), cons(X325, T99)) → DEL43_IN_AAA(X324, X326, T99)

R is empty.
The argument filtering Pi contains the following mapping:
cons(x1, x2)  =  cons(x2)
DEL43_IN_AAA(x1, x2, x3)  =  DEL43_IN_AAA

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

(19) PiDPToQDPProof (SOUND transformation)

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

(20) Obligation:

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

DEL43_IN_AAADEL43_IN_AAA

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 = DEL43_IN_AAA evaluates to t =DEL43_IN_AAA

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 DEL43_IN_AAA to DEL43_IN_AAA.

(36) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

s = U5_A(U10_aa(del34_in_aaa)) evaluates to t =U5_A(U10_aa(del34_in_aaa))

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:
  • Matcher: [ ]
  • Semiunifier: [ ]




Rewriting sequence

U5_A(U10_aa(del34_in_aaa))U5_A(U10_aa(del34_out_aaa))
with rule del34_in_aaadel34_out_aaa at position [0,0] and matcher [ ]

U5_A(U10_aa(del34_out_aaa))U5_A(del229_out_aa)
with rule U10_aa(del34_out_aaa) → del229_out_aa at position [0] and matcher [ ]

U5_A(del229_out_aa)U7_A(del43_out_aaa)
with rule U5_A(del229_out_aa) → U7_A(del43_out_aaa) at position [] and matcher [ ]

U7_A(del43_out_aaa)CONF19_IN_A
with rule U7_A(del43_out_aaa) → CONF19_IN_A at position [] and matcher [ ]

CONF19_IN_AU5_A(U10_aa(del34_in_aaa))
with rule CONF19_IN_AU5_A(U10_aa(del34_in_aaa))

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.

(53) UsableRulesProof (EQUIVALENT transformation)

For (infinitary) constructor rewriting [LOPSTR] we can delete all non-usable rules from R.

(54) Obligation:

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

DEL6_IN_AGA(X72, cons(T25, T26), cons(T25, X73)) → DEL6_IN_AGA(X72, T26, X73)

R is empty.
The argument filtering Pi contains the following mapping:
cons(x1, x2)  =  cons(x2)
DEL6_IN_AGA(x1, x2, x3)  =  DEL6_IN_AGA(x2)

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

(55) PiDPToQDPProof (SOUND transformation)

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

(56) Obligation:

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

DEL6_IN_AGA(cons(T26)) → DEL6_IN_AGA(T26)

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

(57) 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:

  • DEL6_IN_AGA(cons(T26)) → DEL6_IN_AGA(T26)
    The graph contains the following edges 1 > 1

(58) YES

(59) PrologToPiTRSProof (SOUND transformation)

We use the technique of [LOPSTR]. With regard to the inferred argument filtering the predicates were used in the following modes:
conf1_in: (b)
del6_in: (f,b,f)
del18_in: (f,f,b)
conf19_in: (b) (f)
del229_in: (b,f) (f,f)
del34_in: (f,b,f) (f,f,f)
del43_in: (f,f,f)

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

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

(69) Obligation:

The TRS P consists of the following rules:

DEL34_IN_AAADEL34_IN_AAA

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

(70) 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 = DEL34_IN_AAA evaluates to t =DEL34_IN_AAA

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:
  • Matcher: [ ]
  • Semiunifier: [ ]

The DP semiunifies directly so there is only one rewrite step from DEL34_IN_AAA to DEL34_IN_AAA.

del43_in_aaaU9_aaa(del43_in_aaa)
U9_aaa(del43_out_aaa) → del43_out_aaa

The set Q consists of the following terms:

del43_in_aaa
U9_aaa(x0)
U10_aa(x0)
U11_aa(x0)
del34_in_aaa
U12_aa(x0)
U3_aaa(x0)

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

(92) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [FROCOS05] to show that the DP problem is infinite.
Found a loop by narrowing to the left:

s = U5_A(U10_aa(del34_in_aaa)) evaluates to t =U5_A(U10_aa(del34_in_aaa))

Thus s starts an infinite chain as s semiunifies with t with the following substitutions:
  • Semiunifier: [ ]
  • Matcher: [ ]




Rewriting sequence

U5_A(U10_aa(del34_in_aaa))U5_A(U10_aa(del34_out_aaa))
with rule del34_in_aaadel34_out_aaa at position [0,0] and matcher [ ]

U5_A(U10_aa(del34_out_aaa))U5_A(del229_out_aa)
with rule U10_aa(del34_out_aaa) → del229_out_aa at position [0] and matcher [ ]

U5_A(del229_out_aa)U7_A(del43_out_aaa)
with rule U5_A(del229_out_aa) → U7_A(del43_out_aaa) at position [] and matcher [ ]

U7_A(del43_out_aaa)CONF19_IN_A
with rule U7_A(del43_out_aaa) → CONF19_IN_A at position [] and matcher [ ]

CONF19_IN_AU5_A(U10_aa(del34_in_aaa))
with rule CONF19_IN_AU5_A(U10_aa(del34_in_aaa))

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.
