Struct Config 

pub struct Config {
    pub num_samples: NumSamples,
    pub adjust_rate: AdjustRate,
    pub mutation_chance: MutationChance,
    pub mutation_adjust_rate: MutationAdjustRate,
}

PBIL configuration parameters.

Fields

num_samples: NumSamples

Number of samples generated during steps.

adjust_rate: AdjustRate

Degree to adjust probabilities towards best point during steps.

mutation_chance: MutationChance

Probability for each probability to mutate, independently.

mutation_adjust_rate: MutationAdjustRate

Degree to adjust probability towards random value when mutating.

Implementations

impl Config

pub fn new( num_samples: NumSamples, adjust_rate: AdjustRate, mutation_chance: MutationChance, mutation_adjust_rate: MutationAdjustRate, ) -> Self

Return a new PBIL configuration.

impl Config

pub fn default_for(num_bits: usize) -> Self

Return default ‘Config’.

pub fn start_default_for<B, F>(len: usize, obj_func: F) -> Pbil<B, F>

where F: Fn(&[bool]) -> B,

Return this optimizer default running on the given problem.

Arguments

• len: number of bits in each point
• obj_func: objective function to minimize

pub fn start<B, F>(self, len: usize, obj_func: F) -> Pbil<B, F>

where F: Fn(&[bool]) -> B,

Return this optimizer running on the given problem.

This may be nondeterministic.

Arguments

• len: number of bits in each point
• obj_func: objective function to minimize

pub fn start_using<B, F>( self, len: usize, obj_func: F, rng: &mut SplitMix64, ) -> Pbil<B, F>

where F: Fn(&[bool]) -> B,

Return this optimizer running on the given problem initialized using rng.

Arguments

• len: number of bits in each point
• obj_func: objective function to minimize
• rng: source of randomness

pub fn start_from<B, F>(self, obj_func: F, state: State<B>) -> Pbil<B, F>

where F: Fn(&[bool]) -> B,

Return this optimizer running on the given problem. if the given state is valid.

Arguments

• obj_func: objective function to minimize
• state: PBIL state to start from

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Ord for Config

fn cmp(&self, other: &Config) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Config

fn eq(&self, other: &Config) -> 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 Config

fn partial_cmp(&self, other: &Config) -> 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 Eq for Config
