Struct PropagationConfig 

pub struct PropagationConfig {
    pub max_depth: usize,
    pub edge_types: Vec<EdgeType>,
    pub min_delta: f32,
    pub max_affected: usize,
    pub caused_dampening: f32,
    pub supports_factor: f32,
    pub contradicts_factor: f32,
    pub supersedes_floor: f32,
}

Configuration for belief propagation.

Fields

max_depth: usize

Maximum BFS depth for propagation (default: 5).

edge_types: Vec<EdgeType>

Outgoing edge types the walk follows (default: Caused and Supports, the dependency edges). Any other edge type is ignored.

The dependency edges are the default because they are the only ones whose meaning survives a change in the source’s confidence: an effect or a supported claim is only as believable as what it rests on. Contradicts and Supersedes record a conflict that was already resolved, and walking them from a memory that just lost a conflict would move the memories it once contradicted or replaced on no new evidence. They can be added back here explicitly.

min_delta: f32

Smallest per memory change propagate_delta records or walks past (default: 0.01). A damped change below this stops that branch.

max_affected: usize

Most memories one propagate_delta call may change, root excluded (default: 64). The walk stops once it has this many.

caused_dampening: f32

Dampening factor for Caused edges (default: 0.9).

supports_factor: f32

Factor for Supports edges (default: 0.5).

contradicts_factor: f32

Factor for Contradicts edges (default: 0.7).

supersedes_floor: f32

Floor multiplier for Supersedes edges (default: 0.1).

Implementations

impl PropagationConfig

pub fn all_edges() -> Self

The defaults with every belief carrying edge type followed (Caused, Supports, Contradicts, Supersedes), the edge set of propagate_update.

Trait Implementations

impl Clone for PropagationConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PropagationConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PropagationConfig

fn default() -> Self

Returns the “default value” for a type.
