Struct DifferentialEvolution

Source

pub struct DifferentialEvolution<'a, F>where
    F: Fn(&Array1<f64>) -> f64 + Sync,
{ /* private fields */ }

Expand description

Differential Evolution optimizer.

A population-based stochastic optimizer for continuous functions. Use DifferentialEvolution::new to create an instance, configure with config_mut, then call solve.

Implementations§

Source §

impl<'a, F> DifferentialEvolution<'a, F>
where F: Fn(&Array1<f64>) -> f64 + Sync,

Source

pub fn new(func: &'a F, lower: Array1<f64>, upper: Array1<f64>) -> Result<Self>

Creates a new DE optimizer with objective func and bounds [lower, upper].

§Errors

Returns DEError::BoundsMismatch if lower and upper have different lengths. Returns DEError::InvalidBounds if any lower bound exceeds its corresponding upper bound.

Source

pub fn config_mut(&mut self) -> &mut DEConfig

Mutable access to configuration

Source

pub fn solve(&mut self) -> DEReport

Run the optimization and return a report
