innermost

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

As a result of transforming the rule

one new Dependency Pair is created:

FAC(s(x)) -> FAC(p(s(x)))

FAC(s(x)) -> FAC(x)

The transformation is resulting in one new DP problem:

R

↳DPs

→DP Problem 1

↳Rw

→DP Problem 2

↳Forward Instantiation Transformation

**FAC(s( x)) -> FAC(x)**

p(s(x)) ->x

fac(0) -> s(0)

fac(s(x)) -> times(s(x), fac(p(s(x))))

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:

FAC(s(x)) -> FAC(x)

FAC(s(s(x''))) -> FAC(s(x''))

The transformation is resulting in one new DP problem:

R

↳DPs

→DP Problem 1

↳Rw

→DP Problem 2

↳FwdInst

→DP Problem 3

↳Polynomial Ordering

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

p(s(x)) ->x

fac(0) -> s(0)

fac(s(x)) -> times(s(x), fac(p(s(x))))

innermost

The following dependency pair can be strictly oriented:

FAC(s(s(x''))) -> FAC(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(FAC(x)_{1})= 1 + x _{1}_{ }^{ }_{ }^{ }POL(s(x)_{1})= 1 + x _{1}_{ }^{ }

resulting in one new DP problem.

Using the Dependency Graph resulted in no new DP problems.
