As can be seen after transforming the QDP problem by semantic labelling [33] and then some rule deleting processors, only certain labelled rules and pairs can be used.
Hence, we only have to consider all unlabelled pairs and rules (without the decreasing rules for quasi-models).

We have to consider all minimal (P,Q,R)-chains.
By using the rule removal processor [15] with the following polynomial ordering [25], at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:
B1.0(b.0(b.1(x))) → B1.0(c.0(a.1(x)))
C1.0(c.1(x)) → B1.0(a.1(x))
Strictly oriented rules of the TRS R:
b.0(b.0(b.1(x))) → b.0(c.0(a.1(x)))
b.1(x) → a.0(a.1(x))
c.0(c.1(x)) → b.0(a.1(x))
Used ordering: POLO with Polynomial interpretation [25]:
POL(A.0(x1)) = 1 + x1
POL(A.1(x1)) = 1 + x1
POL(A1.0(x1)) = x1
POL(B.0(x1)) = x1

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
As can be seen after transforming the QDP problem by semantic labelling [33] and then some rule deleting processors, only certain labelled rules and pairs can be used.
Hence, we only have to consider all unlabelled pairs and rules (without the decreasing rules for quasi-models).

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
As can be seen after transforming the QDP problem by semantic labelling [33] and then some rule deleting processors, only certain labelled rules and pairs can be used.
Hence, we only have to consider all unlabelled pairs and rules (without the decreasing rules for quasi-models).
