Struct LadderOptimizer 

pub struct LadderOptimizer {
    pub vmaf_equivalence_threshold: f32,
    pub vmaf_gap_threshold: f32,
}

Optimises a LadderSpec by removing VMAF-equivalent rungs and inserting intermediate rungs where VMAF gaps are too large.

Fields

vmaf_equivalence_threshold: f32

Rungs closer than this many VMAF points are considered equivalent.

vmaf_gap_threshold: f32

A gap larger than this triggers insertion of an intermediate rung.

Implementations

impl LadderOptimizer

pub fn new() -> Self

Creates an optimizer with default thresholds (5 / 10 VMAF points).

pub fn with_thresholds(equivalence: f32, gap: f32) -> Self

Creates an optimizer with custom thresholds.

pub fn optimize(&self, spec: LadderSpec) -> LadderSpec

Optimises spec in-place: removes near-equivalent rungs, adds intermediate rungs for large VMAF gaps.

pub fn optimize_full(&self, spec: LadderSpec) -> LadderSpec

Optimise with full equivalent-rung removal (non-broken version).
