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.

Q is empty.
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.


FIRST12(s1(X), cons2(Y, Z)) -> FIRST12(X, activate1(Z))
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(0) = 0   
POL(FIRST12(x1, x2)) = 2·x1   
POL(activate1(x1)) = 0   
POL(cons2(x1, x2)) = 0
