Struct Tournament 

pub struct Tournament { /* private fields */ }

Tournament selection: the best of size individuals drawn at random (with replacement).

Larger tournaments give more selection pressure. A size of 1 is random selection.

Implementations

impl Tournament

pub fn new(size: usize) -> Result<Self>

Tournaments of size individuals, at least 1 and at most 2^24, the largest population size.

Errors

Error::InvalidSetting for a size of 0 or above 2^24.

pub fn size(&self) -> usize

The tournament size.
