innermost

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

As a result of transforming the rule

one new Dependency Pair is created:

SUM(s(x)) -> SUM(x)

SUM(s(s(x''))) -> SUM(s(x''))

The transformation is resulting in one new DP problem:

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

As a result of transforming the rule

one new Dependency Pair is created:

↳Polynomial Ordering

**SUM(s(s(s( x'''')))) -> SUM(s(s(x'''')))**

sum(0) -> 0

sum(s(x)) -> +(sqr(s(x)), sum(x))

sum(s(x)) -> +(*(s(x), s(x)), sum(x))

sqr(x) -> *(x,x)

innermost

The following dependency pair can be strictly oriented:

SUM(s(s(s(x'''')))) -> SUM(s(s(x'''')))

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

Used ordering: Polynomial ordering with Polynomial interpretation:

_{ }^{ }POL(SUM(x)_{1})= 1 + x _{1}_{ }^{ }_{ }^{ }POL(s(x)_{1})= 1 + x _{1}_{ }^{ }

resulting in one new DP problem.
