How to tell if this is working?

[jdm1891]

I made a neural net(mind you with no experience at all - complete guesswork, I'm surprised it even starts)

So I have made a neural network which is supposed to add numbers together, I have let it run for 3000 generations and it still gets most answers wrong(although it gets sort of close most of the time)

What would you think the best way to test how well it works would be? How could I improve it?


https://github.com/jdm1891/neuralNet Here is the code if anybody wants to look and improve it.

Any advice would be great because it's barely working right now!

Edit: After comparing the fitness of each generation I see it is jumping around randomly! ie. It isn't working at all
