Added support for async fitness function using Promises #14

Minimal changes to support async fitness fitness functions with promises.

Does this run my fitness functions in parallel? How could I check something like that...

richardklafter commented 6 years ago

It runs all the fitness functions from one generation in parallel. If your fitness function is 100% JS this will not speed anything up but if your fitness function makes network calls or preforms some other async operation they will all be done in parallel.

I used it for tuning the parameters of an AI I built to play a game. In that case, running my fitness function took ~3min and I did it on lots of remote servers.

Yeah, I came to that realization a bit later last night. My fitness function is just javascript that will require some engineering to get to run asynchronously. Thanks for your help.

For those looking for async support, I've forked this repo and rewrote it in TypeScript and added support for async fitness method (including unit tests): https://github.com/Glavin001/genetic-js Hope this helps you, too! 😃
