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.

A__ISNATKIND(s(V1)) → A__ISNATKIND(V1)
A__ISNATKIND(plus(V1, V2)) → A__ISNATKIND(V1)
A__ISNATKIND(plus(V1, V2)) → A__U31(a__isNatKind(V1), V2)

The remaining pairs can at least be oriented weakly.

A__U31(tt, V2) → A__ISNATKIND(V2)

Used ordering: Polynomial interpretation [25,35]:

POL(plus(x₁, x₂)) = 1/4 + (3/2)x_1 + x_2
POL(A__U31(x₁, x₂)) = (1/4)x_2
POL(A__ISNATKIND(x₁)) = (1/4)x_1
POL(U31(x₁, x₂)) = 2 + (4)x_1 + (7/2)x_2
POL(U41(x₁)) = 15/4 + (5/4)x_1
POL(isNatKind(x₁)) = (11/4)x_1
POL(0) = 5/2
POL(a__U32(x₁)) = 13/4 + (13/4)x_1
POL(tt) = 5/2
POL(a__isNatKind(x₁)) = 0
POL(a__U31(x₁, x₂)) = 4 + (3/2)x_1 + (9/4)x_2
POL(a__U41(x₁)) = 1/2 + (5/2)x_1
POL(U32(x₁)) = 1/2 + (4)x_1
POL(s(x₁)) = 1 + (9/4)x_1

The value of delta used in the strict ordering is 1/16.

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.

A__U21(tt, V1) → A__U22(a__isNatKind(V1), V1)

The remaining pairs can at least be oriented weakly.
