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

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

R is empty.
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:

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