     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(0, 1, g(x, y), z) -> F(g(x, y), g(x, y), g(x, y), h(x))
F(0, 1, g(x, y), z) -> H(x)
H(g(x, y)) -> H(x)

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pair:

H(g(x, y)) -> H(x)


Rules:


f(0, 1, g(x, y), z) -> f(g(x, y), g(x, y), g(x, y), h(x))
g(0, 1) -> 0
g(0, 1) -> 1
h(g(x, y)) -> h(x)


Strategy:

innermost




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

H(g(x, y)) -> H(x)
one new Dependency Pair is created:

H(g(g(x'', y''), y)) -> H(g(x'', y''))

The transformation is resulting in one new DP problem:

           →DP Problem 2
             ↳Forward Instantiation Transformation


Dependency Pair:

H(g(g(x'', y''), y)) -> H(g(x'', y''))


Rules:


f(0, 1, g(x, y), z) -> f(g(x, y), g(x, y), g(x, y), h(x))
g(0, 1) -> 0
g(0, 1) -> 1
h(g(x, y)) -> h(x)


Strategy:

innermost




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

H(g(g(x'', y''), y)) -> H(g(x'', y''))
one new Dependency Pair is created:

H(g(g(g(x'''', y''''), y''0), y)) -> H(g(g(x'''', y''''), y''0))

The transformation is resulting in one new DP problem:

           →DP Problem 2

               →DP Problem 3
                 ↳Polynomial Ordering


Dependency Pair:

H(g(g(g(x'''', y''''), y''0), y)) -> H(g(g(x'''', y''''), y''0))


Rules:


f(0, 1, g(x, y), z) -> f(g(x, y), g(x, y), g(x, y), h(x))
g(0, 1) -> 0
g(0, 1) -> 1
h(g(x, y)) -> h(x)


Strategy:

innermost




The following dependency pair can be strictly oriented:

H(g(g(g(x'''', y''''), y''0), y)) -> H(g(g(x'''', y''''), y''0))


Additionally, the following usable rules for innermost w.r.t. to the implicit AFS can be oriented:

g(0, 1) -> 0
g(0, 1) -> 1


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(0)=  0  
  POL(g(x1, x2))=  1 + x1  
  POL(1)=  0  
  POL(H(x1))=  1 + x1  

resulting in one new DP problem.

g(0, 1) -> 0
