(10) UsableRulesProof (EQUIVALENT transformation)

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

(11) Obligation:

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

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

R is empty.
The argument filtering Pi contains the following mapping:
.(x1, x2) = .(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_AAA → DEL34_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.

(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:

Semiunifier: [ ]
Matcher: [ ]

Rewriting sequence

U5_A(U10_aa(del34_in_aaa)) → U5_A(U10_aa(del34_out_aaa))
with rule del34_in_aaa → del34_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_A → U5_A(U10_aa(del34_in_aaa))
with rule CONF19_IN_A → U5_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.

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

R is empty.
The argument filtering Pi contains the following mapping:
.(x1, x2) = .(x2)
DEL34_IN_AAA(x1, x2, x3) = DEL34_IN_AAA

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