   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(x, y, f(z, u, v)) -> F(f(x, y, z), u, f(x, y, v))
F(x, y, f(z, u, v)) -> F(x, y, z)
F(x, y, f(z, u, v)) -> F(x, y, v)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pairs:

F(x, y, f(z, u, v)) -> F(x, y, z)
F(x, y, f(z, u, v)) -> F(f(x, y, z), u, f(x, y, v))


Rule:


f(x, y, f(z, u, v)) -> f(f(x, y, z), u, f(x, y, v))


Strategy:

innermost




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

F(x, y, f(z, u, v)) -> F(x, y, z)
one new Dependency Pair is created:

F(x'', y'', f(f(z'', u'', v''), u, v)) -> F(x'', y'', f(z'', u'', v''))

The transformation is resulting in one new DP problem:

         ↳FwdInst
           →DP Problem 2
             ↳Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

F(x'', y'', f(f(z'', u'', v''), u, v)) -> F(x'', y'', f(z'', u'', v''))
F(x, y, f(z, u, v)) -> F(f(x, y, z), u, f(x, y, v))


Rule:


f(x, y, f(z, u, v)) -> f(f(x, y, z), u, f(x, y, v))


Strategy:

innermost
