   R
     ↳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. 


   R
     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation 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 Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

C(b(a(X))) -> C(c(X))
no new Dependency Pairs are created.
The transformation is resulting in one new DP problem:

       →DP Problem 1
         ↳FwdInst
           →DP Problem 2
             ↳Forward Instantiation Transformation


Dependency Pair:

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





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

C(b(a(X))) -> C(X)
one new Dependency Pair is created:

C(b(a(b(x'')))) -> C(b(x''))

The transformation is resulting in one new DP problem: 



   R
     ↳DPs
       →DP Problem 1
         ↳FwdInst
           →DP Problem 2
             ↳FwdInst
             ...
               →DP Problem 3
                 ↳Remaining Obligation(s)




The following remains to be proven:
Dependency Pair:

C(b(a(b(x'')))) -> C(b(x''))


Rules:


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