About A.I. used in game programming
Dear all,
I want to ask about some A.I. skill in game programming.
I now designing a BOTs, which is a A.I. player, it will be trained and playing specific games. Such as Counter Strike or Warcraft.
But before I design the algorithm, actually I choose genetic algorithm as my A.I. algorithm ( which I am familiar in), I want to ask,
1. What should I declared as my chromosome?
2. What should I declared the fitness function?
Thank You
Actually I am familiar in G.A. but not so familiar in the game programming or developing.......
Thanks for your attention~

Quote: | Actually I am familiar in G.A. but not so familiar in the game programming or developing....... | Yet your questions are about GA and not game programming. Are you really referring to genetic algorithms and not neural networks? They might both operate on a chromosome, but the essence is vastly different.

Hi,
welcome to Devshed.
FYI, the sticky at the top of this particular forum has a link to AI Resources & Books, which you might find interesting.
I think most good bots for CS have used neural nets as opposed to GA's.

I know Neutral Network is better in Game A.I. Design...
I read some books, one of them called "Game Programming Gems". It also introduce using neutral network instead of Genetic Algorithm.
But I haven't study anything about neutral network before.
So I choose G.A. as a BOT A.I. design....
Actually it is hard to imagine how to declare the chromosome in the context of the game. Which part of the BOTs need to evolution?
For Example, The moving paths of the BOTs will evolue due to training of algorithm, how can I declare a fitness function such that I can test it is more and more fitness to the game??

Quote: | Actually it is hard to imagine how to declare the chromosome in the context of the game. Which part of the BOTs need to evolution? | Whatever the bot can do. So what can it do? It can move. It can shoot. It can pick up objects. It's whatever the game allows it to do.
Quote: | The moving paths of the BOTs will evolue due to training of algorithm, how can I declare a fitness function such that I can test it is more and more fitness to the game?? | Start simple. If your fitness function evaluates a million things, progress will be slow or nil. Increase complexity cautiously.

Thanks a lot
I got a little idea for my A.I. design...
But is it fast enough for the G.A seperate run for different parameter of the game?
Such as moving path, shooting and picking up object?
