Struct SearcherCore 

pub struct SearcherCore<TUnit, TFit, TMover>
where
    TUnit: Unit,
    TFit: FitCalc,
    TMover: ParticleMover,
{
    pub fit_calc: TFit,
    pub mover: TMover,
    pub swarm_best: Best<TUnit>,
    pub master_rng: SmallRng,
    pub particle_rngs: Vec<SmallRng>,
}

Shared bookkeeping for Searcher impls.

Holds the fitness function, mover, master + per-particle RNGs, and the reduced swarm best. Topology-specific state (niche partition, neighbour graph, pbest snapshot) lives on each searcher alongside a SearcherCore field.

Fields

fit_calc: TFit

Fitness function.

mover: TMover

Mover.

swarm_best: Best<TUnit>

Reduced from particle pbests. For gbest this is the social attractor; for lbest / niched it’s reporting only.

master_rng: SmallRng

Source for the per-particle RNGs.

particle_rngs: Vec<SmallRng>

One RNG per particle, sized lazily.

Implementations

impl<TUnit, TFit, TMover> SearcherCore<TUnit, TFit, TMover>

where TUnit: Unit, TFit: FitCalc<T = TUnit>, TMover: ParticleMover<TUnit = TUnit>,

pub fn new(fit_calc: TFit, mover: TMover) -> Self

OS-seeded master RNG; per-particle RNGs are created lazily on the first Self::sync_rngs.

pub fn sync_rngs(&mut self, n: usize)

Resize particle_rngs to n, reseeding new entries from master_rng.

pub fn reseed<R: Rng>(&mut self, rng: &mut R)

Reseed master_rng from rng; per-particle RNGs are cleared and re-derived on the next sync_rngs.

Trait Implementations

impl<TUnit, TFit, TMover> Clone for SearcherCore<TUnit, TFit, TMover>

where TUnit: Unit + Clone, TFit: FitCalc + Clone, TMover: ParticleMover + Clone,

fn clone(&self) -> SearcherCore<TUnit, TFit, TMover>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<TUnit, TFit, TMover, TContext> Contextful for SearcherCore<TUnit, TFit, TMover>

where TFit: FitCalc<T = TUnit, TContext = TContext>, TMover: ParticleMover<TUnit = TUnit, TContext = TContext>, TUnit: Unit, TContext: Copy,

type TContext = TContext

Reparameterization payload.

fn set_context(&mut self, context: Self::TContext)

Replace the current context. Defaults to a no-op; override when the impl actually reads TContext.

fn set_iteration(&mut self, iteration: usize, max_iteration: usize)

iteration is 1-based; the init (fitness-only) pass runs before any call. Override for iteration-dependent schedules.

impl<TUnit, TFit, TMover> Debug for SearcherCore<TUnit, TFit, TMover>

where TUnit: Unit + Debug, TFit: FitCalc + Debug, TMover: ParticleMover + Debug,

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

Formats the value using the given formatter.
