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 (and indeed has been) 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.
Hints on installing and running it.
npm install nodeoYou can also clone it from this repo:
git clone git@github.com:JJ/nodeo.gitIf you have downloaded it from npm, it's already tested. If you have cloned it,
npm install
npm testThere's a simple evolutionary algorithm in the app directory of this
repository. Run
node app/ea.js
or
node app/classic-ea.js
from the command line, for the version with a bit more complicated data structures and no cached fitness function (lighter on the memory front).
You can try and add your own stuff to the library. Start here
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
npm install -g grunt-cliAnd 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.
Please use GitHub issues and I'll try to help you. Can't guarantee I'll be in Gitter, but if that's your thing, please go ahead and try it, I'll arrive eventually.
