NodEO

Evolutionary Algorithm, simplified, for node

NodEO includes the functions necessary to create a simple evolutionary algorithm in JavaScript in CommonJS format, for node.js and anything else that uses that format. Can be converted to the browser using Browserify. Check out the presentation I did for FOSDEM in case you want to know more about evolutionary algorithms and how they have been implemented in JavaScript.

Build Status

Installation

bash npm install nodeo

Testing

bash npm test

Developing

You will have to install a bit of more stuff, including Grunt, which, for the time being, is used to check code and generate documentation. That is bash npm install -g grunt-cli

And then

grunt docco

to generate documentation (if you’ve installed docco previously) or

grunt jshint

to check the code or

grunt browsify

to generate a browser-ready evolutionary algorithm based on the classic version.

Running an evolutionary algorithm

There’s a simple evolutionary algorithm in the app directory,

cd node_modules/nodeo
node app/ea.js

or

node app/classic-ea.js

for the version with a bit more complicated data structures and no cached fitness function (lighter on the memory front).
