Detailed Description
template<typename Real>
class ROL::ReducedLinearConstraint< Real >
Reduce the input of a linear constraint based on the active set associated with a vector \(x\), i.e., let \(\mathcal{I}\) denote the inactive set associated with \(x\) and the bounds \(\ell\le u\), then.
\[ C(v) = c(v_\mathcal{I}), \]
where \form#122 denotes the vector that is equal to
\(v\) on \(\mathcal{I}\) and zero otherwise.
