We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


ACTIVATE1(n__cons2(X1, X2)) -> ACTIVATE1(X1)
ACTIVATE1(n__from1(X)) -> ACTIVATE1(X)
ACTIVATE1(n__s1(X)) -> ACTIVATE1(X)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(ACTIVATE1(x1)) = 2·x1   
POL(n__cons2(x1, x2)) = 2 + 2·x1   
POL(n__from1(x1)) = 2 + 2·x1   
POL(n__s1(x1)) = 2 + 2·x1   

The following usable rules [14] were oriented: none
