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.

MARK(incr(X)) → A__INCR(mark(X))
MARK(s(X)) → MARK(X)
A__ODDNS → A__INCR(a__pairNs)
MARK(incr(X)) → MARK(X)
MARK(cons(X1, X2)) → MARK(X1)
MARK(oddNs) → A__ODDNS

The remaining pairs can at least be oriented weakly.

A__INCR(cons(X, XS)) → MARK(X)

Used ordering: Polynomial interpretation [25,35]:

POL(zip(x₁, x₂)) = 4 + (4)x_1 + (4)x_2
POL(tail(x₁)) = 2 + (4)x_1
POL(A__INCR(x₁)) = (1/4)x_1
POL(A__ODDNS) = 3/4
POL(a__tail(x₁)) = 2 + (4)x_1
POL(a__oddNs) = 4
POL(mark(x₁)) = x_1
POL(oddNs) = 4
POL(a__pairNs) = 5/2
POL(take(x₁, x₂)) = 4 + (4)x_1 + x_2
POL(repItems(x₁)) = (3/2)x_1
POL(0) = 0
POL(a__take(x₁, x₂)) = 4 + (4)x_1 + x_2
POL(cons(x₁, x₂)) = 1 + x_1 + (1/4)x_2
POL(MARK(x₁)) = 1/4 + (1/4)x_1
POL(a__incr(x₁)) = 1/4 + (5/4)x_1
POL(incr(x₁)) = 1/4 + (5/4)x_1
POL(a__repItems(x₁)) = (3/2)x_1
POL(pair(x₁, x₂)) = 1/4 + (13/4)x_1 + (1/2)x_2
POL(s(x₁)) = 1/4 + x_1
POL(a__zip(x₁, x₂)) = 4 + (4)x_1 + (4)x_2
POL(pairNs) = 5/2
POL(nil) = 11/4

The value of delta used in the strict ordering is 1/16.
The following usable rules [17] were oriented:

a__pairNs → cons(0, incr(oddNs))
a__incr(cons(X, XS)) → cons(s(mark(X)), incr(XS))
a__oddNs → a__incr(a__pairNs)
a__take(s(N), cons(X, XS)) → cons(mark(X), take(N, XS))
a__take(0, XS) → nil
a__zip(cons(X, XS), cons(Y, YS)) → cons(pair(mark(X), mark(Y)), zip(XS, YS))
a__zip(nil, XS) → nil
a__zip(X, nil) → nil
mark(pairNs) → a__pairNs
mark(incr(X)) → a__incr(mark(X))
a__repItems(nil) → nil
a__repItems(cons(X, XS)) → cons(mark(X), cons(X, repItems(XS)))
mark(zip(X1, X2)) → a__zip(mark(X1), mark(X2))
a__tail(cons(X, XS)) → mark(XS)
mark(tail(X)) → a__tail(mark(X))
mark(oddNs) → a__oddNs

mark(cons(X1, X2)) → cons(mark(X1), X2)
