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.


ACTIVE1(fib12(X1, X2)) -> ACTIVE1(X1)
ACTIVE1(sel2(X1, X2)) -> ACTIVE1(X2)
ACTIVE1(cons2(X1, X2)) -> ACTIVE1(X1)

ACTIVE1(add2(X1, X2)) -> ACTIVE1(X1)
ACTIVE1(sel2(X1, X2)) -> ACTIVE1(X1)
ACTIVE1(fib1(X)) -> ACTIVE1(X)
ACTIVE1(s1(X)) -> ACTIVE1(X)
ACTIVE1(add2(X1, X2)) -> ACTIVE1(X2)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(ACTIVE1(x1)) = x1   
POL(add2(x1, x2)) = 1 + x1 + x2   
POL(cons2(x1, x2)) = 1 + x1   
POL(fib1(x1)) = 1 + x1   
POL(fib12(x1, x2)) = 1 + x1 + x2   
POL(s1(x1)) = 1 + x1   
POL(sel2(x1, x2)) = 1 + x1 + x2   

The following usable rules [14] were oriented: none
