Enum Sampler 

pub enum Sampler {
    Grid(Grid),
    Random(Random),
    Halton(Halton),
    Sobol(Sobol),
    Tpe(Tpe),
}

Whichever of the schemes a sampler is.

Variants

Grid(Grid)

Grid: every combination, then nothing.

Random(Random)

Random: uniform, looking at nothing.

Halton(Halton)

Halton: spread on purpose, one prime per knob.

Sobol(Sobol)

Sobol: spread on purpose, and without Halton’s seam.

Tpe(Tpe)

Tpe: guided by what already worked.

Implementations

impl Sampler

pub fn ask( &self, space: &Space, trial: usize, seen: &[(Point, Option<f64>)], ) -> Option<Point>

Where to look for the trial-th time, or None when there is nowhere left. seen is the points somebody has already been to, and a score that is not there means the trial is still running. Four of the five ignore the argument, which is the point of having five.

Trait Implementations

impl Clone for Sampler

fn clone(&self) -> Sampler

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sampler

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

Formats the value using the given formatter.

impl Display for Sampler

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

As text, which is the form that goes into the record of a run.

impl From<Grid> for Sampler

fn from(how: Grid) -> Self

Converts to this type from the input type.

impl From<Halton> for Sampler

fn from(how: Halton) -> Self

Converts to this type from the input type.

impl From<Random> for Sampler

fn from(how: Random) -> Self

Converts to this type from the input type.

impl From<Sobol> for Sampler

fn from(how: Sobol) -> Self

Converts to this type from the input type.

impl From<Tpe> for Sampler

fn from(how: Tpe) -> Self

Converts to this type from the input type.

impl PartialEq for Sampler

fn eq(&self, other: &Sampler) -> 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 StructuralPartialEq for Sampler
