Q restricted rewrite system:
The TRS R consists of the following rules:

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

Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

B2(x, y) -> A2(c1(y), a2(0, x))
B2(x, y) -> A2(0, x)
A2(y, c1(b2(a2(0, x), 0))) -> B2(0, y)
A2(y, c1(b2(a2(0, x), 0))) -> A2(c1(b2(0, y)), x)
A2(y, c1(b2(a2(0, x), 0))) -> B2(a2(c1(b2(0, y)), x), 0)

The TRS R consists of the following rules:

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

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