Problem 1: DependencyGraph



Dependency Pair Problem

Dependency Pairs

T(f(g(f(a))))f#(g(f(a)))T(g(x_1))T(x_1)
T(f(x_1))T(x_1)T(f(a))f#(a)

Rewrite Rules

f(f(a))c(f(g(f(a))))

Original Signature

Termination of terms over the following signature is verified: f, g, c, a

Strategy

Context-sensitive strategy:
μ(T) = μ(c) = μ(a) = ∅
μ(f) = μ(g) = μ(f#) = {1}


The following SCCs where found

T(g(x_1)) → T(x_1)T(f(x_1)) → T(x_1)

Problem 2: PolynomialLinearRange4



Dependency Pair Problem

Dependency Pairs

T(g(x_1))T(x_1)T(f(x_1))T(x_1)

Rewrite Rules

f(f(a))c(f(g(f(a))))

Original Signature

Termination of terms over the following signature is verified: f, g, c, a

Strategy

Context-sensitive strategy:
μ(T) = μ(c) = μ(a) = ∅
μ(f) = μ(g) = μ(f#) = {1}


Polynomial Interpretation

There are no usable rules

The following dependency pairs are strictly oriented by an ordering on the given polynomial interpretation, thus they are removed:

T(f(x_1))T(x_1)

Problem 3: PolynomialLinearRange4



Dependency Pair Problem

Dependency Pairs

T(g(x_1))T(x_1)

Rewrite Rules

Strategy

Context-sensitive strategy:
μ(T) = μ(c) = μ(a) = ∅
μ(f) = μ(g) = μ(f#) = {1}


Polynomial Interpretation

There are no usable rules

The following dependency pairs are strictly oriented by an ordering on the given polynomial interpretation, thus they are removed:

T(g(x_1))T(x_1)
