Struct yamakan::optimizers::nelder_mead::NelderMeadOptimizer

pub struct NelderMeadOptimizer<V> { /* fields omitted */ }

An optimizer based on Adaptive Nelder-Mead Simplex (ANMS) algorithm.

Implementations

impl<V> NelderMeadOptimizer<V> where
    V: Ord, 

pub fn new<R: Rng>(params_domain: Vec<ContinuousDomain>, rng: R) -> Result<Self>

Makes a new NelderMeadOptimizer.

pub fn with_initial_point(
    params_domain: Vec<ContinuousDomain>,
    point: &[f64]
) -> Result<Self>

Makes a new NelderMeadOptimizer which has the given search point.

pub fn with_initial_simplex(
    params_domain: Vec<ContinuousDomain>,
    initial_simplex: Vec<Vec<f64>>
) -> Result<Self>

Makes a new NelderMeadOptimizer with the given simplex.
