AmdOptions

Struct AmdOptions 

Source
pub struct AmdOptions {
    pub aggressive: bool,
    pub dense_alpha: f64,
}
Expand description

Tunable parameters for AMD ordering.

Defaults match faer / SuiteSparse: aggressive = true, dense_alpha = 10.0.

Fields§

§aggressive: bool

Enable aggressive element absorption in the Pass-2 degree loop (faer amd.rs:404-407).

§dense_alpha: f64

Dense-row threshold multiplier. A variable with initial degree exceeding min(max(16, floor(dense_alpha * sqrt(n))), n) is deferred to the end of the ordering — the max(16) floor is applied before the min(n) cap, matching faer amd.rs:173-179 / SuiteSparse AMD (the order matters: it guarantees the threshold is <= n). A negative value uses a raw threshold of n - 2 in place of dense_alpha * sqrt(n), with the same max(16)/min(n) clamps; for n >= 18 that is exactly n - 2, suppressing deferral for all but true hubs of degree n - 1.
