ActiveRowDependence

gam_solve::active_set

Struct ActiveRowDependence 

Source 
pub struct ActiveRowDependence {
    pub active_pos: usize,
    pub coeff: f64,
}
Expand description

One dependent row of the WORKING SET expressed against its representative: a_dep ≈ coeff · a_rep.

Recorded ONLY for exactly-parallel (positively-aligned scalar-multiple) dependents; a general-position dependent is dropped from the working set with NO entry and re-enters via the next feasibility scan (it never receives a distributed/phantom multiplier).

active_pos is an ACTIVE-SET POSITION: an index into the caller’s active slice, so the original constraint id is active[active_pos] (see [compress_active_working_set], which seeds groups with exactly these positions). It is NOT a constraint-row id and NOT a coefficient index. The reduced-face op reports its dependents in constraint-row space instead and therefore uses its own ConstraintRowDependence — the two must not be interchanged.
