Struct Nsga2Sampler 

pub struct Nsga2Sampler { /* private fields */ }

NSGA-II sampler for multi-objective optimization.

Use non-dominated sorting with crowding-distance tie-breaking to evolve a well-spread Pareto front. Best suited for bi-objective problems; for 3+ objectives prefer Nsga3Sampler.

Create with Nsga2Sampler::new, Nsga2Sampler::with_seed, or Nsga2Sampler::builder for full configuration.

Implementations

impl Nsga2Sampler

pub fn new() -> Self

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

pub fn with_seed(seed: u64) -> Self

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

pub fn builder() -> Nsga2SamplerBuilder

Creates a builder for configuring an Nsga2Sampler.

Trait Implementations

impl Default for Nsga2Sampler

fn default() -> Self

Returns the “default value” for a type.

impl MultiObjectiveSampler for Nsga2Sampler

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

Samples a parameter value from the given distribution.
