   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

APP(app(app(compose, f), g), x) -> APP(f, app(g, x))
APP(app(app(compose, f), g), x) -> APP(g, x)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pairs:

APP(app(app(compose, f), g), x) -> APP(g, x)
APP(app(app(compose, f), g), x) -> APP(f, app(g, x))


Rule:


app(app(app(compose, f), g), x) -> app(f, app(g, x))


Strategy:

innermost




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

APP(app(app(compose, f), g), x) -> APP(g, x)
one new Dependency Pair is created:

APP(app(app(compose, f), app(app(compose, f''), g'')), x'') -> APP(app(app(compose, f''), g''), x'')

The transformation is resulting in one new DP problem: 



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




The following remains to be proven:
Dependency Pairs:

APP(app(app(compose, f), app(app(compose, f''), g'')), x'') -> APP(app(app(compose, f''), g''), x'')
APP(app(app(compose, f), g), x) -> APP(f, app(g, x))


Rule:


app(app(app(compose, f), g), x) -> app(f, app(g, x))


Strategy:

innermost
