On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

ACTIVATE(n_{_s}(n_{_from}(n_{_from}(X'''')))) -> ACTIVATE(n_{_from}(n_{_from}(X'''')))

three new Dependency Pairs are created:

ACTIVATE(n_{_s}(n_{_from}(n_{_from}(n_{_from}(X''''''))))) -> ACTIVATE(n_{_from}(n_{_from}(n_{_from}(X''''''))))
ACTIVATE(n_{_s}(n_{_from}(n_{_from}(n_{_s}(X''''''))))) -> ACTIVATE(n_{_from}(n_{_from}(n_{_s}(X''''''))))

On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

five new Dependency Pairs are created:

On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

ACTIVATE(n_{_cons}(n_{_s}(n_{_from}(n_{_from}(X''''''))), X2)) -> ACTIVATE(n_{_s}(n_{_from}(n_{_from}(X''''''))))

three new Dependency Pairs are created:

ACTIVATE(n_{_cons}(n_{_s}(n_{_from}(n_{_from}(n_{_from}(X'''''''')))), X2)) -> ACTIVATE(n_{_s}(n_{_from}(n_{_from}(n_{_from}(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

ACTIVATE(n_{_cons}(n_{_s}(n_{_from}(n_{_s}(X''''''))), X2)) -> ACTIVATE(n_{_s}(n_{_from}(n_{_s}(X''''''))))

five new Dependency Pairs are created:

ACTIVATE(n_{_cons}(n_{_s}(n_{_from}(n_{_s}(n_{_s}(X'''''''')))), X2)) -> ACTIVATE(n_{_s}(n_{_from}(n_{_s}(n_{_s}(X'''''''')))))
