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

We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


A2(0, x) -> C1(x)
The remaining pairs can at least be oriented weakly.

C1(c1(b1(c1(x)))) -> A2(0, c1(x))
A2(0, x) -> C1(c1(x))
Used ordering: Polynomial interpretation [21]:

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

The following usable rules [14] were oriented:

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