We have to consider all minimal (P,Q,R)-chains.

Used ordering: Polynomial interpretation [21]:

POL(ACTIVE₁(x₁)) = 2·x₁
POL(cons₂(x₁, x₂)) = 2 + 2·x₁
POL(from₁(x₁)) = 2 + 2·x₁
POL(minus₂(x₁, x₂)) = 2 + 2·x₁ + 2·x₂
POL(quot₂(x₁, x₂)) = 2 + 2·x₁ + 2·x₂
POL(s₁(x₁)) = 2 + 2·x₁
POL(sel₂(x₁, x₂)) = 2 + 2·x₁ + 2·x₂
POL(zWquot₂(x₁, x₂)) = 2 + 2·x₁ + 2·x₂
