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

(6) QDPOrderProof (EQUIVALENT transformation)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

A__U91(tt, V2) → A__ISPALLISTKIND(V2)
A__ISPALLISTKIND(__(V1, V2)) → A__U91(a__isPalListKind(V1), V2)
A__ISPALLISTKIND(__(V1, V2)) → A__ISPALLISTKIND(V1)

The remaining pairs can at least be oriented weakly.
Used ordering: SCNP Order with the following components:
Level mapping:
Top level AFS:
A__U91(x0, x1, x2) = A__U91(x2)
A__ISPALLISTKIND(x0, x1) = A__ISPALLISTKIND(x0, x1)

Tags:
A__U91 has argument tags [0,2,2] and root tag 1
A__ISPALLISTKIND has argument tags [4,2] and root tag 0

Comparison: MIN
Underlying order for the size change arcs and the rules of R:
Combined order from the following AFS and order.
A__U91(x1, x2) = x1
tt = tt
A__ISPALLISTKIND(x1) = A__ISPALLISTKIND(x1)
__(x1, x2) = __(x1, x2)
a__isPalListKind(x1) = x1
a = a
e = e
i = i
nil = nil
o = o
u = u
a__U91(x1, x2) = a__U91(x1, x2)
isPalListKind(x1) = isPalListKind
a__U92(x1) = a__U92(x1)
U91(x1, x2) = U91(x1, x2)
U92(x1) = U92

Lexicographic path order with status [LPO].
Quasi-Precedence:

[_{_₂}, a_{_U91₂}] > A_{_{ISPALLISTKIND₁}} > isPalListKind
[_{_₂}, a_{_U91₂}] > a_{_U92₁} > [tt, i, o] > isPalListKind
[_{_₂}, a_{_U91₂}] > a_{_U92₁} > U92 > isPalListKind
[_{_₂}, a_{_U91₂}] > U91₂ > isPalListKind
a > [tt, i, o] > isPalListKind
e > [tt, i, o] > isPalListKind
nil > [tt, i, o] > isPalListKind
u > [tt, i, o] > isPalListKind

Status:

tt: []
A_{_{ISPALLISTKIND₁}}: [1]
__₂: [2,1]

u: []
a_{_U91₂}: [2,1]
isPalListKind: []

The following usable rules [FROCOS05] were oriented:

a__isPalListKind(a) → tt

a__isPalListKind(i) → tt
a__isPalListKind(nil) → tt
a__isPalListKind(o) → tt

a__isPalListKind(__(V1, V2)) → a__U91(a__isPalListKind(V1), V2)
a__isPalListKind(X) → isPalListKind(X)
a__U91(tt, V2) → a__U92(a__isPalListKind(V2))
a__U91(X1, X2) → U91(X1, X2)

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

A__ISNEPAL(__(I, __(P, I))) → A__U71(a__isQid(I), I, P)
A__U71(tt, I, P) → A__U72(a__isPalListKind(I), P)

A__U81(tt, V) → A__U82(a__isPalListKind(V), V)
A__U82(tt, V) → A__ISNEPAL(V)

The remaining pairs can at least be oriented weakly.
Used ordering: SCNP Order with the following components:

A__U81(x0, x1, x2) = A__U81(x2)
A__U82(x0, x1, x2) = A__U82(x2)

A__ISNEPAL has argument tags [5,20] and root tag 2
A__U71 has argument tags [22,11,8,16] and root tag 5

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

MARK(U21(X1, X2, X3)) → MARK(X1)

The remaining pairs can at least be oriented weakly.
Used ordering: SCNP Order with the following components:

We use the reduction pair processor [LPAR04].

The following pairs can be oriented strictly and are deleted.

MARK(U31(X1, X2)) → MARK(X1)

The remaining pairs can at least be oriented weakly.
Used ordering: SCNP Order with the following components:
Level mapping:
