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

Q 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(b₁(x)))) -> C₁(x)
B₁(c₁(b₁(c₁(x)))) -> A₂(1, x)
A₂(1, x) -> B₁(x)
A₂(0, x) -> C₁(x)
C₁(c₁(c₁(b₁(x)))) -> B₁(c₁(x))

The remaining pairs can at least be oriented weakly.

A₂(1, x) -> C₁(b₁(x))
C₁(c₁(c₁(b₁(x)))) -> A₂(1, b₁(c₁(x)))
B₁(c₁(b₁(c₁(x)))) -> A₂(0, a₂(1, x))
A₂(0, x) -> C₁(c₁(x))

Used ordering: Polynomial interpretation [21]:

POL(0) = 1
POL(1) = 1
POL(A₂(x₁, x₂)) = x₁ + x₂
POL(B₁(x₁)) = x₁
POL(C₁(x₁)) = x₁
POL(a₂(x₁, x₂)) = 1 + x₁ + x₂
POL(b₁(x₁)) = 1 + x₁
POL(c₁(x₁)) = 1 + x₁

The following usable rules [14] were oriented:

a₂(0, x) -> c₁(c₁(x))
b₁(c₁(b₁(c₁(x)))) -> a₂(0, a₂(1, x))
a₂(1, x) -> c₁(b₁(x))
c₁(c₁(c₁(b₁(x)))) -> a₂(1, b₁(c₁(x)))
