   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(f(x)) -> F(c(f(x)))
F(f(x)) -> F(d(f(x)))
G(c(h(0))) -> G(d(1))
G(c(1)) -> G(d(h(0)))
G(h(x)) -> G(x)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pair:

G(h(x)) -> G(x)


Rules:


f(f(x)) -> f(c(f(x)))
f(f(x)) -> f(d(f(x)))
g(c(x)) -> x
g(d(x)) -> x
g(c(h(0))) -> g(d(1))
g(c(1)) -> g(d(h(0)))
g(h(x)) -> g(x)


Strategy:

innermost




The following dependency pair can be strictly oriented:

G(h(x)) -> G(x)


There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(G(x1))=  x1  
  POL(h(x1))=  1 + x1  

resulting in one new DP problem.
Used Argument Filtering System:
G(x1) -> G(x1)
h(x1) -> h(x1)

Dependency Pair:


Rules:


f(f(x)) -> f(c(f(x)))
f(f(x)) -> f(d(f(x)))
g(c(x)) -> x
g(d(x)) -> x
g(c(h(0))) -> g(d(1))
g(c(1)) -> g(d(h(0)))
g(h(x)) -> g(x)


Strategy:

Using the Dependency Graph resulted in no new DP problems.
