The preamble to src/main.rs is typical for the programs we've seen so far in this book:
extern crate feruscore;
extern crate rand;
extern crate rayon;
use feruscore::individual::*;
use rand::{thread_rng, Rng};
use rayon::prelude::*;
use std::collections::VecDeque;
use std::fs::File;
use std::fs::{self, DirBuilder};
use std::io::{self, BufWriter};
use std::path::{Path, PathBuf};
use std::sync::atomic::{AtomicUsize, Ordering};
use std::{thread, time};
The program does start, however, with an abnormally large block of constants and statics:
// configuration const POPULATION_SIZE: u16 = 256; // NOTE must be powers of two const CHROMOSOME_SIZE: u16 = 25; // Must be <= 100 const PARENTS: u16 = POPULATION_SIZE / 8; const CHILDREN: u16 = PARENTS ...
