Problem 1: DependencyGraph



Dependency Pair Problem

Dependency Pairs

g#(s(X)) → g#(X)sel#(s(X), cons(Y, Z)) → activate#(Z)
f#(X) → g#(X)activate#(n__f(X)) → f#(X)
sel#(s(X), cons(Y, Z)) → sel#(X, activate(Z))

Rewrite Rules

f(X) → cons(X, n__f(g(X)))g(0) → s(0)
g(s(X)) → s(s(g(X)))sel(0, cons(X, Y)) → X
sel(s(X), cons(Y, Z)) → sel(X, activate(Z))f(X) → n__f(X)
activate(n__f(X)) → f(X)activate(X) → X

Original Signature

Termination of terms over the following signature is verified: f, activate, g, 0, s, sel, n__f, cons

Strategy


The following SCCs where found

g#(s(X)) → g#(X)

sel#(s(X), cons(Y, Z)) → sel#(X, activate(Z))

Problem 2: SubtermCriterion



Dependency Pair Problem

Dependency Pairs

sel#(s(X), cons(Y, Z)) → sel#(X, activate(Z))

Rewrite Rules

f(X) → cons(X, n__f(g(X)))g(0) → s(0)
g(s(X)) → s(s(g(X)))sel(0, cons(X, Y)) → X
sel(s(X), cons(Y, Z)) → sel(X, activate(Z))f(X) → n__f(X)
activate(n__f(X)) → f(X)activate(X) → X

Original Signature

Termination of terms over the following signature is verified: f, activate, g, 0, s, sel, n__f, cons

Strategy


Projection

The following projection was used:

Thus, the following dependency pairs are removed:

sel#(s(X), cons(Y, Z)) → sel#(X, activate(Z))

Problem 3: SubtermCriterion



Dependency Pair Problem

Dependency Pairs

g#(s(X)) → g#(X)

Rewrite Rules

f(X) → cons(X, n__f(g(X)))g(0) → s(0)
g(s(X)) → s(s(g(X)))sel(0, cons(X, Y)) → X
sel(s(X), cons(Y, Z)) → sel(X, activate(Z))f(X) → n__f(X)
activate(n__f(X)) → f(X)activate(X) → X

Original Signature

Termination of terms over the following signature is verified: f, activate, g, 0, s, sel, n__f, cons

Strategy


Projection

The following projection was used:

Thus, the following dependency pairs are removed:

g#(s(X)) → g#(X)
