We have to consider all minimal (P,Q,R)-chains.
We can use the usable rules and reduction pair processor [15] with the Ce-compatible extension of the polynomial order that maps every function symbol to the sum of its argument. Then, we can delete all non-usable rules [17] from R.

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

FCONS(X1, mark(X2)) → FCONS(X1, X2)
The graph contains the following edges 1 >= 1, 2 > 2
FCONS(X1, active(X2)) → FCONS(X1, X2)
The graph contains the following edges 1 >= 1, 2 > 2
FCONS(active(X1), X2) → FCONS(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
FCONS(mark(X1), X2) → FCONS(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2

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

UNQUOTE1(active(X)) → UNQUOTE1(X)
UNQUOTE1(mark(X)) → UNQUOTE1(X)

From the DPs we obtained the following set of size-change graphs:

UNQUOTE1(active(X)) → UNQUOTE1(X)
The graph contains the following edges 1 > 1
UNQUOTE1(mark(X)) → UNQUOTE1(X)
The graph contains the following edges 1 > 1

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

QUOTE1(mark(X)) → QUOTE1(X)
QUOTE1(active(X)) → QUOTE1(X)

From the DPs we obtained the following set of size-change graphs:

QUOTE1(mark(X)) → QUOTE1(X)
The graph contains the following edges 1 > 1
QUOTE1(active(X)) → QUOTE1(X)
The graph contains the following edges 1 > 1

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

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

From the DPs we obtained the following set of size-change graphs:

CONS(X1, active(X2)) → CONS(X1, X2)
The graph contains the following edges 1 >= 1, 2 > 2
CONS(mark(X1), X2) → CONS(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
CONS(active(X1), X2) → CONS(X1, X2)
The graph contains the following edges 1 > 1, 2 >= 2
CONS(X1, mark(X2)) → CONS(X1, X2)
The graph contains the following edges 1 >= 1, 2 > 2

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.
