Struct AmgOptions 

pub struct AmgOptions {
    pub strength_threshold: f64,
    pub max_levels: usize,
    pub max_coarse: usize,
    pub smooth_omega: f64,
    pub pre_sweeps: usize,
    pub post_sweeps: usize,
}

Tunable parameters for the smoothed-aggregation setup and the V-cycle.

Fields

strength_threshold: f64

Strength-of-connection threshold θ (e.g. 0.08).

max_levels: usize

Maximum number of levels (including the finest) before forcing a coarse solve.

max_coarse: usize

Stop coarsening once the operator order is ≤ max_coarse.

smooth_omega: f64

Prolongator-smoothing weight numerator; the effective Jacobi weight is smooth_omega / ρ̂(D⁻¹A) (e.g. smooth_omega = 4/3).

pre_sweeps: usize

Number of pre-smoothing sweeps per level.

post_sweeps: usize

Number of post-smoothing sweeps per level.

Trait Implementations

impl Default for AmgOptions

fn default() -> Self
