Struct ADMM 

pub struct ADMM {
    pub rho: f64,
    pub max_iter: usize,
    pub tol: f64,
}

Alternating Direction Method of Multipliers (consensus form).

Fields

rho: f64

Penalty parameter ρ > 0.

max_iter: usize

Maximum number of iterations.

tol: f64

Convergence tolerance.

Implementations

impl ADMM

pub fn new(rho: f64) -> Self

Create an ADMM solver with penalty rho.

pub fn solve_lasso(&self, a: &[Vec<f64>], b: &[f64], lambda: f64) -> Vec<f64>

Solve the LASSO problem: minimize 0.5‖Ax − b‖² + λ‖x‖₁.

This is a stub that returns the zero vector (placeholder).

Trait Implementations

fn clone(&self) -> ADMM

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ADMM

fn fmt(&self, f: &mut Formatter<'_>) -> Result
