Dependency Pair Analysis



R contains the following Dependency Pairs:

F(s(0), g(x)) -> F(x, g(x))
G(s(x)) -> G(x)

Furthermore, R contains one SCC.

DPs
       →DP Problem 1
Forward Instantiation Transformation


Dependency Pair:

G(s(x)) -> G(x)


Rules:


f(s(0), g(x)) -> f(x, g(x))
g(s(x)) -> g(x)


Strategy:

innermost




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

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

G(s(s(x''))) -> G(s(x''))

The transformation is resulting in one new DP problem:

Forward Instantiation Transformation


Dependency Pair:

G(s(s(x''))) -> G(s(x''))


Rules:


f(s(0), g(x)) -> f(x, g(x))
g(s(x)) -> g(x)


Strategy:

innermost




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

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

G(s(s(s(x'''')))) -> G(s(s(x'''')))

The transformation is resulting in one new DP problem:

Polynomial Ordering


Dependency Pair:

G(s(s(s(x'''')))) -> G(s(s(x'''')))


Rules:


f(s(0), g(x)) -> f(x, g(x))
g(s(x)) -> g(x)


Strategy:

innermost




The following dependency pair can be strictly oriented:

G(s(s(s(x'''')))) -> G(s(s(x'''')))


There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(G(x1))=  1 + x1  
  POL(s(x1))=  1 + x1  

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rules:


f(s(0), g(x)) -> f(x, g(x))
g(s(x)) -> g(x)


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
