Term Rewriting System R:
[y, x]
f(0, y) -> 0
f(s(x), y) -> f(f(x, y), y)
Termination of R to be shown.
R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(s(x), y) -> F(f(x, y), y)
F(s(x), y) -> F(x, y)
Furthermore, R contains one SCC.

↳Argument Filtering and Ordering
Dependency Pairs:
F(s(x), y) -> F(x, y)
F(s(x), y) -> F(f(x, y), y)
Rules:
f(0, y) -> 0
f(s(x), y) -> f(f(x, y), y)
The following dependency pairs can be strictly oriented:
F(s(x), y) -> F(x, y)
F(s(x), y) -> F(f(x, y), y)
The following rules can be oriented:
f(0, y) -> 0
f(s(x), y) -> f(f(x, y), y)
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System: F(x1, x2) -> F(x1, x2)
s(x1) -> s(x1)
f(x1, x2) -> x1

↳Dependency Graph
Dependency Pair:
Rules:
f(0, y) -> 0
f(s(x), y) -> f(f(x, y), y)
Using the Dependency Graph resulted in no new DP problems.
