Struct Environment 

pub struct Environment {
    pub name: String,
    pub weights: Vec<[f64; 3]>,
}

A named environment with its own fitness weights.

Fields

name: String

weights: Vec<[f64; 3]>

Per-position weights. Length should match strategy vector length. For each position, weights[0] = value of 0, weights[1] = value of 1, weights[2] = value of 2.

Implementations

impl Environment

pub fn simple(len: usize) -> Self

Create a simple environment where each position values 2 > 1 > 0.

pub fn diagonal(len: usize) -> Self

An environment that rewards the “diagonal” pattern: position i prefers value i%3.

pub fn zeros(len: usize) -> Self

All zeros preferred.

pub fn random_seeded(len: usize, seed: u64) -> Self

Random environment with given seed.

pub fn evaluate(&self, strategy: &[u8]) -> f64

Evaluate the fitness of a strategy in this environment.

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Environment

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

Formats the value using the given formatter.
