Struct CloneSingle 

pub struct CloneSingle {
    pub num_selected: u32,
}

Select the single individual in the population num_selected times.

This is useful for cloning the current individual in a single-solution-based metaheuristic and then performing some operation on each cloned individual e.g. for generating multiple neighbors.

Errors

The component returns an Err if the population does not contain exactly one individual.

Fields

num_selected: u32

Number of times the single individual is cloned.

Implementations

impl CloneSingle

pub fn from_params(num_selected: u32) -> Self

pub fn new<P: Problem>(num_selected: u32) -> Box<dyn Component<P>>

Trait Implementations

impl Clone for CloneSingle

fn clone(&self) -> CloneSingle
