We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

P₂(a₁(x0), p₂(b₁(x1), p₂(a₁(x2), x3))) -> P₂(a₁(a₁(x0)), p₂(b₁(x1), x3))

The remaining pairs can at least be oriented weakly.

P₂(a₁(x0), p₂(b₁(x1), p₂(a₁(x2), x3))) -> P₂(x2, p₂(a₁(a₁(x0)), p₂(b₁(x1), x3)))

Used ordering: Polynomial interpretation [21]:

POL(P₂(x₁, x₂)) = x₂
POL(a₁(x₁)) = 2·x₁
POL(b₁(x₁)) = 2
