Term Rewriting System R:
[x, y]
f(g(x), s(0), y) -> f(y, y, g(x))
g(s(x)) -> s(g(x))
g(0) -> 0

Termination of R to be shown. 



   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains two SCCs.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering
       →DP Problem 2
         ↳Remaining


Dependency Pair:

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


Rules:


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





The following dependency pair can be strictly oriented:

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


The following rules can be oriented:

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


Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
{g, s}

resulting in one new DP problem.
Used Argument Filtering System:
G(x1) -> G(x1)
s(x1) -> s(x1)
f(x1, x2, x3) -> f
g(x1) -> g(x1)

Dependency Pair:


Rules:


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





Using the Dependency Graph resulted in no new DP problems.

The following remains to be proven:
Dependency Pair:

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


Rules:


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