`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

C(b(a(X))) -> A(a(b(b(c(c(X))))))
C(b(a(X))) -> A(b(b(c(c(X)))))
C(b(a(X))) -> B(b(c(c(X))))
C(b(a(X))) -> B(c(c(X)))
C(b(a(X))) -> C(c(X))
C(b(a(X))) -> C(X)

Furthermore, R contains one SCC.

`     ↳DPs`
`       →DP Problem 1`
`         ↳Narrowing Transformation`

Dependency Pairs:

C(b(a(X))) -> C(X)
C(b(a(X))) -> C(c(X))

Rules:

c(b(a(X))) -> a(a(b(b(c(c(X))))))
c(X) -> e
a(X) -> e
b(X) -> e

On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule

C(b(a(X))) -> C(c(X))
two new Dependency Pairs are created:

C(b(a(b(a(X''))))) -> C(a(a(b(b(c(c(X'')))))))
C(b(a(X''))) -> C(e)

The transformation is resulting in one new DP problem:

`   R`
`     ↳DPs`
`       →DP Problem 1`
`         ↳Nar`
`           →DP Problem 2`
`             ↳Remaining Obligation(s)`

The following remains to be proven:
Dependency Pairs:

C(b(a(b(a(X''))))) -> C(a(a(b(b(c(c(X'')))))))
C(b(a(X))) -> C(X)

Rules:

c(b(a(X))) -> a(a(b(b(c(c(X))))))
c(X) -> e
a(X) -> e
b(X) -> e
