     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(g(x, y)) -> G(f(x), f(y))
F(g(x, y)) -> F(x)
F(g(x, y)) -> F(y)
F(h(x, y)) -> G(h(y, f(x)), h(x, f(y)))
F(h(x, y)) -> F(x)
F(h(x, y)) -> F(y)

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pairs:

F(h(x, y)) -> F(y)
F(h(x, y)) -> F(x)
F(g(x, y)) -> F(y)
F(g(x, y)) -> F(x)


Rules:


f(a) -> b
f(c) -> d
f(g(x, y)) -> g(f(x), f(y))
f(h(x, y)) -> g(h(y, f(x)), h(x, f(y)))
g(x, x) -> h(e, x)





The following dependency pairs can be strictly oriented:

F(h(x, y)) -> F(y)
F(h(x, y)) -> F(x)
F(g(x, y)) -> F(y)
F(g(x, y)) -> F(x)


There are no usable rules w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System:
F(x1) -> F(x1)
h(x1, x2) -> h(x1, x2)
g(x1, x2) -> g(x1, x2)

Dependency Pair:


Rules:


f(a) -> b
f(c) -> d
f(g(x, y)) -> g(f(x), f(y))
f(h(x, y)) -> g(h(y, f(x)), h(x, f(y)))
g(x, x) -> h(e, x)





Using the Dependency Graph resulted in no new DP problems.
