%description
An implementation of the fast structural filtering with L0 penalty. It
includes an adaptive polynomial estimator by minimizing the least squares
error with constraints on the number of breaks in their (k + 1)-st
discrete derivative, for a chosen integer k >= 0. It also includes
generalized structure sparsity constraint, i.e., graph trend filtering.
This package is implemented via the primal dual active set algorithm,
which formulates estimates and residuals as primal and dual variables, and
utilizes efficient active set selection strategies based on the properties
of the primal and dual variables.
