g(s(x)) -> g(x)

     ↳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 two SCCs.

       →DP Problem 2
         ↳NonTerm


Dependency Pair:

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


Rules:


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





We number the DPs as follows:
  1. G(s(x)) -> G(x)
and get the following Size-Change Graph(s):
{1} , {1}
1>1

which lead(s) to this/these maximal multigraph(s):
{1} , {1}
1>1

DP: empty set
Oriented Rules: none

We used the order Homeomorphic Embedding Order with Non-Strict Precedence.
trivial

with Argument Filtering System:
s(x1) -> s(x1)

We obtain no new DP problems.

         ↳Non Termination


Dependency Pair:

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


Rules:


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





Found an infinite P-chain over R:
P =

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

R =

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

s = F(s(0), g(s(0)))
evaluates to t =F(s(0), g(s(0)))

Thus, s starts an infinite chain.

Non-Termination of R could be shown.
