Struct AntColonyPermutation 

pub struct AntColonyPermutation<B: Backend> { /* private fields */ }

Ant Colony Optimization for permutation problems (TSP, QAP, …).

Not yet implemented — planned for a future release.

Panics

All Strategy methods except best invoke todo!(). The struct is constructible (new, Default) and useful for declaring downstream API surface; do not drive it through a harness.

Example

use burn::backend::Flex;
use rlevo_evolution::algorithms::metaheuristic::aco_perm::{AntColonyPermutation, AcoPermConfig};

let strategy = AntColonyPermutation::<Flex>::new();
let params = AcoPermConfig::default_for(32, 20);
let _ = (strategy, params);

Implementations

impl<B: Backend> AntColonyPermutation<B>

pub fn new() -> Self

Builds a new (stateless) strategy object (stub; all methods todo!()).

Trait Implementations

impl<B: Clone + Backend> Clone for AntColonyPermutation<B>

fn clone(&self) -> AntColonyPermutation<B>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<B: Copy + Backend> Copy for AntColonyPermutation<B>

impl<B: Debug + Backend> Debug for AntColonyPermutation<B>

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

Formats the value using the given formatter.

impl<B: Default + Backend> Default for AntColonyPermutation<B>

fn default() -> AntColonyPermutation<B>

Returns the “default value” for a type.

impl<B: Backend> Strategy<B> for AntColonyPermutation<B>

type Params = AcoPermConfig

Static parameters for a run.

type State = AcoPermState<B>

Generation-to-generation state.

type Genome = Tensor<B, 2, Int>

Genome container produced by ask.

fn init( &self, _params: &AcoPermConfig, _rng: &mut dyn Rng, _device: &<B as BackendTypes>::Device, ) -> AcoPermState<B>

Build the initial state.

fn ask( &self, _params: &AcoPermConfig, _state: &AcoPermState<B>, _rng: &mut dyn Rng, _device: &<B as BackendTypes>::Device, ) -> (Self::Genome, AcoPermState<B>)

Propose the next population.

fn tell( &self, _params: &AcoPermConfig, _population: Self::Genome, _fitness: Tensor<B, 1>, _state: AcoPermState<B>, _rng: &mut dyn Rng, ) -> (AcoPermState<B>, StrategyMetrics)

Consume fitness values and produce the next state.

fn best(&self, _state: &AcoPermState<B>) -> Option<(Self::Genome, f32)>

Best-so-far accessor.
