hey
I teach Game Development (Programming C#) at MAD Faculty in Belgium.
I started this summer with AI, mainly Neural Nets.
Now trying my first Genetic Algorithm.

here's a sim i did with using a Monty hall type of choosing as input for a ANN.
there are 3 actions to choose from: Eat, Kill, Procreate.
it chooses one of these based on the Monty Hall Problem.
It sends the choice to the neural network, together with the current balance of the environment (i.e. food/population). The net reviews the choice and its impact on the environment and rewards or punishes a decision depend on that impact.
Longest run i did was +2.600.000 generations so i guess it can go on for ever...

guess I'm looking for a community to get some feedback ;-)
cheers

Hello Rottjung

I'm sorry, but required Unity is not available for my Linux.

[rottjung]

should you really want to see it

i use unity as it is a fast and simple way to visualize and interface a program...

Hi and welcome to AiDreams 

I use Unity myself, I'm hoping WebGL will take over with that, I have tried a couple of times but so far Firefox seems to work best with Unity stuff.

thx Freddy,
I'm on mac with chrome, no trouble so far but i do believe chrome's support for the unity player will be ended in the near future.

[Freddy]

Yep it's due to Google dropping the aged npapi thing.

There's no point developing for Chrome using a web player now really, unless people are on older versions of course and they intend to stay on them.

Best to move on.

Welcome Rottjung!

Hope you enjoy your stay with us.

I ran your sim and noticed the number of "units" seems to remain "balanced" between 23 to 40 depending on which activity they happen to be engaged in at the moment.

A lot of the action / changes happen rather quickly and it takes a few moments for one to get the gist of what's transpiring.

Nice demo and interesting project.

Perhaps a method to reward the ones who eat, procreate and then go one to become a stronger, bigger unit/character.
Might be difficult to keep the bully syndrome from kicking in or taking over but at any rate it would be interesting to watch.

Anyhow, welcome and keep up the good work!

hey Art,
thanks for trying :-)
yes you can up the population by increasing the food supplied.
It was just a test for the monty hall problem, although I'm not sure if it is relevant once the neural net starts adjusting bias toward a needed action.
I was actually looking for a very very simple way of implementing a probability field, "inspired" by heisenberg uncertainty principle: that with the most chance of happening will happen, until then everything can happen...
so with monty hall i tried looking at it as if every door holds a 1 and a 0 until you open up one, if it's not 1 the other doors chances increase...
