Petri: Evolutionary Computing Toolkit
Tools for running evolutionary algorithms
Please read the API documentation
Note: This project is currently a work in progress. If somehow you stumble upon this library: you should not use this library as its incomplete and the API is not stable.
Usage
// Import what algorithms we're going to use
use petri::algo::{Simple, EvolutionaryAlgorithm};
use petri::ops::select::Tournament;
use petri::ops::crossover::TwoPoint;
use petri::ops::mutate::FlipBit;
use rand::thread_rng;
// Create the fitness function to evaluate a genome with
fn fitness_fn(genome: &Vec<bool>) -> u32
{
let mut ones = 0;
for c in genome {
if c {
ones += 1;
}
}
ones
}
// Create the runner
let mut gen_runner = Simple::new(
Tournament::with_size(3),
TwoPoint::default(),
FlipBit::with_pb(0.02),
fitness_fn,
0.01,
0.05,
300,
thread_rng()
);
// Initialize population
gen_runner.initialize(300, || vec![false; 100]);
// run the algorithm
while !gen_runner.is_done() {
let _ = gen_runner.next();
}
// View our final population
println!("{:?}", gen_runner.population());
