        parent_id: u64,
    },

}

Source of a candidate’s genome.

Variants

Random

Drawn uniformly from the space.

Restart

Drawn uniformly from the space when a hill climb starts over.

Neighbor

A step away from hill climb incumbent parent_id.

Fields

parent_id: u64

Id of the incumbent the step starts from.

Mutation

Candidate parent_id with some genes changed.

Fields

parent_id: u64

Id of the candidate the genes come from.

Crossover

Genes taken from two parents, then mutated.

Fields

first_parent_id: u64

Id of the parent that won the first tournament.

second_parent_id: u64

Id of the parent that won the second tournament.

Reevaluation

More replicates of candidate candidate_id.

Fields

candidate_id: u64

Id of the candidate evaluated again.

Implementations

impl CandidateOrigin

pub fn as_str(self) -> &'static str

Returns the origin’s name in evaluations.csv, as in crossover.

pub fn parent_ids(self) -> [Option<u64>; 2]

Returns the ids of the parents the genome was bred from, the first parent first.

A re-evaluation has no parents. Self::reevaluated_id returns the id of the candidate it repeats.

pub fn reevaluated_id(self) -> Option<u64>

Returns the candidate a re-evaluation adds replicates to, or None for any other origin.

Trait Implementations

impl Clone for CandidateOrigin

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Copy for CandidateOrigin

impl Debug for CandidateOrigin

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

Formats the value using the given formatter.

impl Eq for CandidateOrigin

impl PartialEq for CandidateOrigin

fn eq(&self, other: &Self) -> bool
