PSO struct

contains methods for performing Particle Swarm Optimization

Fields

model: Model

neigh_population: Population

best_f_values: Vec<f64>

best_f_trajectory: Vec<f64>

best_x_trajectory: Vec<Particle>

Implementations

impl PSO

pub fn new(model: Model) -> PSO

Initialize Particle Swarm Optimization

pub fn run(&mut self, terminate: fn(_: f64) -> bool) -> usize

Performs Particle Swarm Optimization

Panics

Panics if any particle coefficient becomes NaN

pub fn write_f_to_file(&self, filepath: &str) -> Result<(), Box<dyn Error>>

Writes the best found objective function value for all iterations separated by newline characters

pub fn write_x_to_file(&self, filepath: &str) -> Result<(), Box<dyn Error>>

Writes the best found minimizer for all iterations

Vector coefficients are comma-separated, and the best vector at each iteration is terminated with a newline character
