Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

ISNATLIST(ok(X)) → ISNATLIST(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ISNATLIST(x₁)) = (4)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

ISNATILIST(ok(X)) → ISNATILIST(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ISNATILIST(x₁)) = (4)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

ISNAT(ok(X)) → ISNAT(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 1 + (4)x_1
POL(ISNAT(x₁)) = (4)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

ISNATILISTKIND(ok(X)) → ISNATILISTKIND(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ISNATILISTKIND(x₁)) = (4)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

ISNATKIND(ok(X)) → ISNATKIND(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ISNATKIND(x₁)) = (4)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U96¹(mark(X)) → U96¹(X)
U96¹(ok(X)) → U96¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + x_1
POL(ok(x₁)) = 4 + (4)x_1
POL(U96¹(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U95¹(ok(X1), ok(X2)) → U95¹(X1, X2)
U95¹(mark(X1), X2) → U95¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 1 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(U95¹(x₁, x₂)) = (4)x_1 + x_2

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U94¹(mark(X1), X2, X3) → U94¹(X1, X2, X3)
U94¹(ok(X1), ok(X2), ok(X3)) → U94¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U94¹(x₁, x₂, x₃)) = (4)x_1 + (4)x_2 + x_3
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (2)x_1

The value of delta used in the strict ordering is 9.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U93¹(ok(X1), ok(X2), ok(X3)) → U93¹(X1, X2, X3)
U93¹(mark(X1), X2, X3) → U93¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U93¹(x₁, x₂, x₃)) = (4)x_1 + (4)x_2 + x_3
POL(ok(x₁)) = 1 + (2)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 9.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U92¹(ok(X1), ok(X2), ok(X3)) → U92¹(X1, X2, X3)
U92¹(mark(X1), X2, X3) → U92¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 1 + (4)x_1
POL(mark(x₁)) = 4 + (2)x_1
POL(U92¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + x_3

The value of delta used in the strict ordering is 8.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U91¹(mark(X1), X2, X3) → U91¹(X1, X2, X3)
U91¹(ok(X1), ok(X2), ok(X3)) → U91¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U91¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + x_3
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 8.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U81¹(mark(X)) → U81¹(X)
U81¹(ok(X)) → U81¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U81¹(x₁)) = (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 4 + x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U71¹(mark(X)) → U71¹(X)
U71¹(ok(X)) → U71¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U71¹(x₁)) = (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 4 + x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U62¹(mark(X)) → U62¹(X)
U62¹(ok(X)) → U62¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + x_1
POL(ok(x₁)) = 4 + (4)x_1
POL(U62¹(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U61¹(mark(X1), X2) → U61¹(X1, X2)
U61¹(ok(X1), ok(X2)) → U61¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U61¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 3 + (4)x_1

The value of delta used in the strict ordering is 15.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U52¹(mark(X)) → U52¹(X)
U52¹(ok(X)) → U52¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U52¹(x₁)) = (4)x_1
POL(mark(x₁)) = 4 + x_1
POL(ok(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U51¹(ok(X1), ok(X2)) → U51¹(X1, X2)
U51¹(mark(X1), X2) → U51¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U51¹(x₁, x₂)) = (4)x_1 + x_2
POL(ok(x₁)) = 1 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U46¹(mark(X)) → U46¹(X)
U46¹(ok(X)) → U46¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U46¹(x₁)) = (4)x_1
POL(mark(x₁)) = 4 + x_1
POL(ok(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U45¹(ok(X1), ok(X2)) → U45¹(X1, X2)
U45¹(mark(X1), X2) → U45¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U45¹(x₁, x₂)) = (4)x_1 + x_2
POL(ok(x₁)) = 3 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 15.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U44¹(mark(X1), X2, X3) → U44¹(X1, X2, X3)
U44¹(ok(X1), ok(X2), ok(X3)) → U44¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U44¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + x_3

The value of delta used in the strict ordering is 8.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U43¹(mark(X1), X2, X3) → U43¹(X1, X2, X3)
U43¹(ok(X1), ok(X2), ok(X3)) → U43¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U43¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + x_3
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 8.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U42¹(mark(X1), X2, X3) → U42¹(X1, X2, X3)
U42¹(ok(X1), ok(X2), ok(X3)) → U42¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U42¹(x₁, x₂, x₃)) = (4)x_1 + (4)x_2 + x_3
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (2)x_1

The value of delta used in the strict ordering is 9.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U41¹(ok(X1), ok(X2), ok(X3)) → U41¹(X1, X2, X3)
U41¹(mark(X1), X2, X3) → U41¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(U41¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U33¹(ok(X)) → U33¹(X)
U33¹(mark(X)) → U33¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U33¹(x₁)) = (4)x_1
POL(ok(x₁)) = 4 + x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U32¹(ok(X1), ok(X2)) → U32¹(X1, X2)
U32¹(mark(X1), X2) → U32¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U32¹(x₁, x₂)) = (4)x_1 + x_2
POL(ok(x₁)) = 1 + (4)x_1
POL(mark(x₁)) = 4 + (2)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

U31¹(ok(X1), ok(X2)) → U31¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U31¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U23¹(ok(X)) → U23¹(X)
U23¹(mark(X)) → U23¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(U23¹(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U22¹(mark(X1), X2) → U22¹(X1, X2)
U22¹(ok(X1), ok(X2)) → U22¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U22¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 3 + (4)x_1

The value of delta used in the strict ordering is 15.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U21¹(ok(X1), ok(X2)) → U21¹(X1, X2)
U21¹(mark(X1), X2) → U21¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U21¹(x₁, x₂)) = (4)x_1 + x_2
POL(ok(x₁)) = 3 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 15.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

TAKE(ok(X1), ok(X2)) → TAKE(X1, X2)
TAKE(mark(X1), X2) → TAKE(X1, X2)
TAKE(X1, mark(X2)) → TAKE(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(TAKE(x₁, x₂)) = (4)x_1 + (4)x_2
POL(ok(x₁)) = 4 + (2)x_1
POL(mark(x₁)) = 4 + (2)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U136¹(mark(X1), X2, X3, X4) → U136¹(X1, X2, X3, X4)
U136¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U136¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 2 + x_1
POL(ok(x₁)) = 1 + (2)x_1
POL(U136¹(x₁, x₂, x₃, x₄)) = (2)x_1 + x_2 + (3)x_3 + x_4

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U135¹(mark(X1), X2, X3, X4) → U135¹(X1, X2, X3, X4)
U135¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U135¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U135¹(x₁, x₂, x₃, x₄)) = (4)x_1 + (3)x_2 + (3)x_3 + (3)x_4

The value of delta used in the strict ordering is 13.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U134¹(mark(X1), X2, X3, X4) → U134¹(X1, X2, X3, X4)
U134¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U134¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U134¹(x₁, x₂, x₃, x₄)) = (4)x_1 + (3)x_2 + (3)x_3 + (3)x_4

The value of delta used in the strict ordering is 13.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U133¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U133¹(X1, X2, X3, X4)
U133¹(mark(X1), X2, X3, X4) → U133¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U133¹(x₁, x₂, x₃, x₄)) = (4)x_1 + (3)x_2 + (3)x_3 + x_4
POL(ok(x₁)) = 1 + x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 11.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U132¹(mark(X1), X2, X3, X4) → U132¹(X1, X2, X3, X4)
U132¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U132¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U132¹(x₁, x₂, x₃, x₄)) = (2)x_1 + x_2 + (3)x_3 + x_4
POL(mark(x₁)) = 2 + x_1
POL(ok(x₁)) = 1 + (2)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U131¹(mark(X1), X2, X3, X4) → U131¹(X1, X2, X3, X4)
U131¹(ok(X1), ok(X2), ok(X3), ok(X4)) → U131¹(X1, X2, X3, X4)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U131¹(x₁, x₂, x₃, x₄)) = (2)x_1 + x_2 + (3)x_3 + x_4
POL(mark(x₁)) = 2 + x_1
POL(ok(x₁)) = 1 + (2)x_1

The value of delta used in the strict ordering is 4.
The following usable rules [17] were oriented: none

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U122¹(mark(X)) → U122¹(X)
U122¹(ok(X)) → U122¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U122¹(x₁)) = (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 4 + x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U121¹(mark(X1), X2) → U121¹(X1, X2)
U121¹(ok(X1), ok(X2)) → U121¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U121¹(x₁, x₂)) = (4)x_1 + x_2

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U13¹(ok(X)) → U13¹(X)
U13¹(mark(X)) → U13¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(U13¹(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

LENGTH(ok(X)) → LENGTH(X)
LENGTH(mark(X)) → LENGTH(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(LENGTH(x₁)) = (4)x_1
POL(ok(x₁)) = 4 + x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

S(ok(X)) → S(X)
S(mark(X)) → S(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(S(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U114¹(mark(X1), X2) → U114¹(X1, X2)
U114¹(ok(X1), ok(X2)) → U114¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U114¹(x₁, x₂)) = (4)x_1 + x_2

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U113¹(mark(X1), X2, X3) → U113¹(X1, X2, X3)
U113¹(ok(X1), ok(X2), ok(X3)) → U113¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U113¹(x₁, x₂, x₃)) = (4)x_1 + (4)x_2 + x_3
POL(mark(x₁)) = 4 + (4)x_1
POL(ok(x₁)) = 1 + (2)x_1

The value of delta used in the strict ordering is 9.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U112¹(mark(X1), X2, X3) → U112¹(X1, X2, X3)
U112¹(ok(X1), ok(X2), ok(X3)) → U112¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U112¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3

The value of delta used in the strict ordering is 10.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U111¹(ok(X1), ok(X2), ok(X3)) → U111¹(X1, X2, X3)
U111¹(mark(X1), X2, X3) → U111¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U111¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3
POL(ok(x₁)) = 4 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U12¹(mark(X1), X2) → U12¹(X1, X2)
U12¹(ok(X1), ok(X2)) → U12¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U12¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U11¹(mark(X1), X2) → U11¹(X1, X2)
U11¹(ok(X1), ok(X2)) → U11¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U11¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U106¹(ok(X)) → U106¹(X)
U106¹(mark(X)) → U106¹(X)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + (4)x_1
POL(mark(x₁)) = 4 + x_1
POL(U106¹(x₁)) = (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U105¹(mark(X1), X2) → U105¹(X1, X2)
U105¹(ok(X1), ok(X2)) → U105¹(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U105¹(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U104¹(ok(X1), ok(X2), ok(X3)) → U104¹(X1, X2, X3)
U104¹(mark(X1), X2, X3) → U104¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U104¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + x_3
POL(ok(x₁)) = 1 + (4)x_1
POL(mark(x₁)) = 4 + (2)x_1

The value of delta used in the strict ordering is 8.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U103¹(ok(X1), ok(X2), ok(X3)) → U103¹(X1, X2, X3)
U103¹(mark(X1), X2, X3) → U103¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(ok(x₁)) = 4 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1
POL(U103¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U102¹(ok(X1), ok(X2), ok(X3)) → U102¹(X1, X2, X3)
U102¹(mark(X1), X2, X3) → U102¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(U102¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3
POL(ok(x₁)) = 4 + (4)x_1
POL(mark(x₁)) = 4 + (4)x_1

The value of delta used in the strict ordering is 16.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

U101¹(mark(X1), X2, X3) → U101¹(X1, X2, X3)
U101¹(ok(X1), ok(X2), ok(X3)) → U101¹(X1, X2, X3)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1
POL(U101¹(x₁, x₂, x₃)) = (4)x_1 + (3)x_2 + (3)x_3

The value of delta used in the strict ordering is 10.
The following usable rules [17] were oriented: none

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

CONS(mark(X1), X2) → CONS(X1, X2)
CONS(ok(X1), ok(X2)) → CONS(X1, X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(CONS(x₁, x₂)) = (4)x_1 + x_2
POL(mark(x₁)) = 4 + (2)x_1
POL(ok(x₁)) = 1 + (4)x_1

The value of delta used in the strict ordering is 5.
The following usable rules [17] were oriented: none
