Struct ParetoFitness 

pub struct ParetoFitness {
    pub objectives: Vec<f64>,
    pub rank: usize,
    pub crowding_distance: f64,
}

Multi-objective fitness value using Pareto ranking

Fields

objectives: Vec<f64>

Objective values (all to be maximized)

rank: usize

Pareto rank (0 = non-dominated front)

crowding_distance: f64

Crowding distance for diversity preservation

Implementations

impl ParetoFitness

pub fn new(objectives: Vec<f64>) -> Self

Create a new Pareto fitness with the given objectives

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

Check if this solution dominates another (all objectives >= and at least one >)

pub fn num_objectives(&self) -> usize

Number of objectives

Trait Implementations

impl Clone for ParetoFitness

fn clone(&self) -> ParetoFitness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParetoFitness

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParetoFitness

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FitnessValue for ParetoFitness

fn to_f64(&self) -> f64

Convert fitness to f64 for probabilistic operations

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

Check if this fitness is better than another

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

Check if this fitness is worse than another

impl PartialEq for ParetoFitness

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ParetoFitness

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ParetoFitness

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
