1.1.1 Reduction Pair Processor

Using the linear polynomial interpretation over the naturals

[f^#(x₁)]	=	2 + 2 · x₁
[g^#(x₁)]	=	2
[k^#(x₁)]	=	2
[s^#(x₁)]	=	2

1.1.1.1 Dependency Graph Processor

The dependency pairs are split into 2 components.

The 1^st component contains the pair
g^#(s(x)) → g^#(x) (24)

1.1.1.1.1 Monotonic Reduction Pair Processor with Usable Rules
Using the linear polynomial interpretation over the naturals

[s(x₁)] = 1 · x₁

[g^#(x₁)] = 1 · x₁

having no usable rules (w.r.t. the implicit argument filter of the reduction pair), the rule could be deleted.
1.1.1.1.1.1 Size-Change Termination

Using size-change termination in combination with the subterm criterion one obtains the following initial size-change graphs.

g^#(s(x)) → g^#(x) (24)

1 > 1

As there is no critical graph in the transitive closure, there are no infinite chains.

The 2^nd component contains the pair

s^#(s(s(s(0))))	→	k^#(s(0))	(29)
k^#(s(0))	→	s^#(s(0))	(30)
s^#(s(s(s(s(s(s(s(s(s(s(0)))))))))))	→	k^#(s(s(0)))	(31)
