Q is empty.
We have to consider all minimal (P,Q,R)-chains.
By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

TOP₁(mark₁(X)) -> TOP₁(proper₁(X))

Used argument filtering: TOP₁(x1) = x1
mark₁(x1) = mark₁(x1)
proper₁(x1) = x1
2nd₁(x1) = x1
cons₂(x1, x2) = x1
from₁(x1) = x1
s₁(x1) = x1
cons1₂(x1, x2) = cons1₂(x1, x2)
ok₁(x1) = ok
Used ordering: Quasi Precedence: cons1_2 > mark_1

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
