Struct pso::PSO

pub struct PSO { /* fields omitted */ }

Particle Swarm Optimizer

Base struct to run optimization jobs using Particle Swarms and an objective function

Implementations

impl PSO

pub fn from_swarm_configs(
    verbose: bool,
    swarm_configs: Vec<SwarmConfig>
) -> Self

Generate a PSO from a list of Swarm Configuartions

pub fn from_swarm_config(
    num_swarms: usize,
    verbose: bool,
    swarm_config: &SwarmConfig
) -> Self

Generate a PSO with num_swarms swarms using the given Swarm Configuration

pub fn default(num_swarms: usize, verbose: bool) -> Self

Generate a PSO with num_swarms swarms using the default Swarm Configuration

pub fn run_job<F>(
    &self,
    job_config: JobConfig,
    objective_function: F
) -> (f64, Vec<f64>) where
    F: Fn(&[f64]) -> f64 + Clone + Sync + Send + 'static, 

Run an optimization with the given Job Configuration and Objective Function

Returns a tuple with the minimum cost and corresponding location in the search space

This function clones the objective function for each swarm before sharing it across threads. This is a performance consideration to reduce the shared use of data within the objective function across multiple threads. It also allows the objective function to internally mutate itself (the function does not have to be Sync+Send)

Trait Implementations

impl Clone for PSO

fn clone(&self) -> PSO

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PSO

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

Formats the value using the given formatter.
