Struct AndersonConfig 

pub struct AndersonConfig {
    pub m: usize,
    pub damping: f32,
    pub ridge: f32,
}

Anderson acceleration configuration for Sinkhorn fixed-point iterations.

This is intended as an optional speed-up for hard regimes (small (\varepsilon)). It does not change the fixed point; it only tries to reach it in fewer iterations.

Notes:

• We apply Anderson to the combined iterate (x = (\log u, \log v)).
• This is a heuristic: it can help a lot, do nothing, or (rarely) hurt.

Fields

m: usize

History size (typical: 3–8).

damping: f32

Damping in ([0,1]). 1.0 = full Anderson step, 0.0 = no acceleration.

ridge: f32

Ridge term added to the normal equations (helps with ill-conditioned history).
