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(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)) = 3·x₁
POL(add₂(x₁, x₂)) = 3 + 2·x₁ + 2·x₂
POL(cons₂(x₁, x₂)) = 3 + 2·x₁
POL(fib₁(x₁)) = 3 + 2·x₁
POL(fib1₂(x₁, x₂)) = 3 + x₁ + 2·x₂
POL(s₁(x₁)) = 3 + 2·x₁
POL(sel₂(x₁, x₂)) = 3 + 2·x₁ + 2·x₂
