Struct Nsga3Sampler 

pub struct Nsga3Sampler { /* private fields */ }

NSGA-III sampler for multi-objective optimization.

Use reference-point niching with Das-Dennis structured points to maintain diversity in many-objective (3+) problems. For bi-objective problems, Nsga2Sampler is simpler.

Create with Nsga3Sampler::new, Nsga3Sampler::with_seed, or Nsga3Sampler::builder for full configuration.

Implementations

impl Nsga3Sampler

pub fn new() -> Self

Creates a new NSGA-III sampler with a random seed.

pub fn with_seed(seed: u64) -> Self

Creates a new NSGA-III sampler with a fixed seed.

pub fn builder() -> Nsga3SamplerBuilder

Creates a builder for configuring an Nsga3Sampler.

Trait Implementations

impl Default for Nsga3Sampler

fn default() -> Self

Returns the “default value” for a type.

impl MultiObjectiveSampler for Nsga3Sampler

fn sample( &self, distribution: &Distribution, trial_id: u64, history: &[MultiObjectiveTrial], directions: &[Direction], ) -> ParamValue

Samples a parameter value from the given distribution.
