(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:

LESS69_IN_AA(s(T128), s(T129)) → LESS69_IN_AA(T128, T129)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1) = s(x1)
LESS69_IN_AA(x1, x2) = LESS69_IN_AA

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:

LESS69_IN_AA → LESS69_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 = LESS69_IN_AA evaluates to t =LESS69_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 LESS69_IN_AA to LESS69_IN_AA.

(27) 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 = ORDERED39_IN_AA evaluates to t =ORDERED39_IN_AA

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

Matcher: [ ]
Semiunifier: [ ]

Rewriting sequence

ORDERED39_IN_AA → U8_AA(less61_out_aa(0))
with rule ORDERED39_IN_AA → U8_AA(less61_out_aa(0)) at position [] and matcher [ ]

U8_AA(less61_out_aa(0)) → ORDERED39_IN_AA
with rule U8_AA(less61_out_aa(T99)) → ORDERED39_IN_AA

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.

By using the rule removal processor [LPAR04] with the following ordering, at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:

PERM38_IN_GA(T69) → U4_GA(app18_in_aaag(T69))
U4_GA(app18_out_aaag(T76, T72, T77)) → U6_GA(app28_in_gga(T76, T77))

app28_in_gga([], T50) → app28_out_gga(T50)

(66) UsableRulesProof (EQUIVALENT transformation)

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

(67) Obligation:

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

LESS69_IN_AA(s(T128), s(T129)) → LESS69_IN_AA(T128, T129)

R is empty.
The argument filtering Pi contains the following mapping:
s(x1) = s(x1)
LESS69_IN_AA(x1, x2) = LESS69_IN_AA

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

(68) PiDPToQDPProof (SOUND transformation)

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

(69) Obligation:

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

LESS69_IN_AA → LESS69_IN_AA

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

(70) NonTerminationProof (EQUIVALENT transformation)

Matcher: [ ]

Rewriting sequence

The DP semiunifies directly so there is only one rewrite step from LESS69_IN_AA to LESS69_IN_AA.

(107) UsableRulesProof (EQUIVALENT transformation)

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

(108) Obligation:

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

PERM38_IN_GA(T69, .(T72, T78)) → U4_GA(T69, T72, T78, app18_in_aaag(T76, T72, T77, T69))

.(x1, x2) = .(x1, x2)
app18_out_aaag(x1, x2, x3, x4) = app18_out_aaag(x1, x2, x3, x4)
U1_aaag(x1, x2, x3, x4, x5, x6) = U1_aaag(x1, x5, x6)
app28_in_gga(x1, x2, x3) = app28_in_gga(x1, x2)
app28_out_gga(x1, x2, x3) = app28_out_gga(x1, x2, x3)
U2_gga(x1, x2, x3, x4, x5) = U2_gga(x1, x2, x3, x5)
PERM38_IN_GA(x1, x2) = PERM38_IN_GA(x1)
U4_GA(x1, x2, x3, x4) = U4_GA(x1, x4)

The remaining pairs can at least be oriented weakly.
Used ordering: Polynomial interpretation [POLO]:

POL(.(x₁, x₂)) = 1 + x₂
POL(PERM38_IN_GA(x₁)) = 1 + x₁
POL(U1_aaag(x₁, x₂, x₃)) = 1 + x₃
POL(U2_gga(x₁, x₂, x₃, x₄)) = 1 + x₄
