Dependency Pair Analysis



R contains the following Dependency Pairs:

F(a, y) -> F(y, g(y))
F(a, y) -> G(y)

Furthermore, R contains one SCC.


   R
DPs
       →DP Problem 1
Forward Instantiation Transformation


Dependency Pair:

F(a, y) -> F(y, g(y))


Rules:


f(a, y) -> f(y, g(y))
g(a) -> b
g(b) -> b





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

F(a, y) -> F(y, g(y))
one new Dependency Pair is created:

F(a, a) -> F(a, g(a))

The transformation is resulting in one new DP problem:

DPs
       →DP Problem 1
FwdInst
           →DP Problem 2
Narrowing Transformation


Dependency Pair:

F(a, a) -> F(a, g(a))


Rules:


f(a, y) -> f(y, g(y))
g(a) -> b
g(b) -> b





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

F(a, a) -> F(a, g(a))
one new Dependency Pair is created:

F(a, a) -> F(a, b)

The transformation is resulting in no new DP problems.
