Struct ExternalArchive 

pub struct ExternalArchive { /* private fields */ }

External archive storing discarded solutions

Implementations

impl ExternalArchive

pub fn new(max_size: usize) -> Self

Create a new empty archive

pub fn with_population_size(np: usize, arc_rate: f64) -> Self

Create archive with size proportional to population

pub fn add(&mut self, solution: Array1<f64>)

Add a solution to the archive If archive is full, removes a random solution

pub fn random_select<R: Rng + ?Sized>( &self, rng: &mut R, ) -> Option<&Array1<f64>>

Select a random solution from the archive Returns None if archive is empty

pub fn random_index<R: Rng + ?Sized>(&self, rng: &mut R) -> Option<usize>

Get a random index for archive selection Returns None if archive is empty, otherwise returns a valid index into the archive

pub fn get(&self, idx: usize) -> Option<&Array1<f64>>

Get solution at index (used after random_index)

pub fn len(&self) -> usize

Number of solutions in archive

pub fn is_empty(&self) -> bool

Check if archive is empty

pub fn clear(&mut self)

Clear the archive

pub fn resize(&mut self, new_max_size: usize)

Resize the archive (keeps existing solutions if new size is larger)
