innermost

The following dependency pair can be strictly oriented:

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

There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:

_{ }^{ }POL(s(x)_{1})= 1 + x _{1}_{ }^{ }_{ }^{ }POL(F(x)_{1}, x_{2})= x _{1}+ x_{2}_{ }^{ }

resulting in one new DP problem.

Used Argument Filtering System:

F(x,_{1}x) -> F(_{2}x,_{1}x)_{2}

s(x) -> s(_{1}x)_{1}

↳Narrowing Transformation

**G(0, x) -> G(f(x, x), x)**

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

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

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

innermost

On this DP problem, a Narrowing SCC transformation can be performed.

As a result of transforming the rule

two new Dependency Pairs are created:

G(0,x) -> G(f(x,x),x)

G(0, 0) -> G(s(0), 0)

G(0, s(x'')) -> G(s(f(x'',x'')), s(x''))

The transformation is resulting in no new DP problems.
