Dependency Pair Analysis



R contains the following Dependency Pairs:

INF(x) -> CONS(x, inf(s(x)))
INF(x) -> INF(s(x))

Furthermore, R contains one SCC.


   R
DPs
       →DP Problem 1
Instantiation Transformation


Dependency Pair:

INF(x) -> INF(s(x))


Rules:


cons(x, cons(y, z)) -> big
inf(x) -> cons(x, inf(s(x)))


Strategy:

innermost




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

INF(x) -> INF(s(x))
one new Dependency Pair is created:

INF(s(x'')) -> INF(s(s(x'')))

The transformation is resulting in one new DP problem:



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




The following remains to be proven:
Dependency Pair:

INF(s(x'')) -> INF(s(s(x'')))


Rules:


cons(x, cons(y, z)) -> big
inf(x) -> cons(x, inf(s(x)))


Strategy:

innermost
