apex_solver::core::noise

Enum RepairStrategy 

Source 
pub enum RepairStrategy {
    Clamp,
    UnitWeight,
}
Expand description

Strategy for handling an indefinite per-edge information matrix.

The repair itself lives in NoiseModel::from_information_reporting; this enum is the single shared vocabulary for choosing what to do with the report, so binaries, benches and libraries stop re-implementing the clamp | unit-weight branch with divergent defaults.

Variants§

§

Clamp

Keep the PSD projection (nearest-PSD clamp). The optimized objective stays the Ω-weighted χ², minus the clamped directions.

§

UnitWeight

Substitute an identity weight for any edge whose Ω needed a material repair. This trades χ² for unweighted cost on those edges — callers must label the reported objective accordingly.

Implementations§

Source§

impl RepairStrategy

Source

pub fn from_name(name: &str) -> CoreResult<Self>

Parse a CLI/env value ("clamp" or "unit-weight", case-insensitive).

Source

pub fn build( &self, info: DMatrix<f64>, ) -> CoreResult<(NoiseModel, InformationRepair)>

Build a noise model from Ω under this strategy, reporting what happened. Returns the model and its InformationRepair; under RepairStrategy::UnitWeight a materially-repaired edge comes back as NoiseModel::Null (identity weight).
