Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:

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.

C₁(c₁(c₁(a₂(x, y)))) -> C₁(c₁(c₁(c₁(y))))
C₁(c₁(c₁(a₂(x, y)))) -> C₁(y)
C₁(c₁(c₁(a₂(x, y)))) -> C₁(c₁(c₁(y)))
C₁(c₁(a₂(a₂(y, 0), x))) -> C₁(y)
C₁(c₁(c₁(a₂(x, y)))) -> C₁(c₁(y))
C₁(c₁(b₂(c₁(y), 0))) -> C₁(c₁(a₂(y, 0)))

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(0) = 0
POL(C₁(x₁)) = 2·x₁²
POL(a₂(x₁, x₂)) = 1 + x₁ + 2·x₂
POL(b₂(x₁, x₂)) = 3 + x₁
POL(c₁(x₁)) = 2·x₁

The following usable rules [14] were oriented:

c₁(c₁(c₁(a₂(x, y)))) -> b₂(c₁(c₁(c₁(c₁(y)))), x)
c₁(c₁(b₂(c₁(y), 0))) -> a₂(0, c₁(c₁(a₂(y, 0))))
c₁(c₁(a₂(a₂(y, 0), x))) -> c₁(y)
