Struct AmfOptions 

pub struct AmfOptions {
    pub dense_alpha: f64,
}

Tunable parameters for AMF ordering.

Defaults: dense_alpha = 10.0. HAMF4 always aggressively absorbs absorbed elements during the inner Pass-2 loop, so there is no aggressive knob.

Fields

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. A negative value uses a raw threshold of n - 2 with the same clamps; for n >= 18 that is exactly n - 2, suppressing deferral for all but true hubs of degree n - 1.
