We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

INC(s(x)) → INC(x)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
INC(x1) = INC(x1)
s(x1) = s(x1)

Recursive path order with status [2].
Precedence:

s₁ > INC₁

Status:

INC₁: multiset
s₁: multiset

The following usable rules [14] were oriented: none
