#5175302 How to make a AI choose?

Posted by IADaveMark on 21 August 2014 - 10:32 AM

"Utility" > "fuzzy"

;)

 

I approve of this.

Enter utility-based AI.

enter utility systems.

 

Any reading suggestions to get a quick overview how utility based systems differ from behaviour trees with "smart" metric-driven transitions?

 

Someone else tell him, please. It's less awkward that way.

Re neural networks: FFS

Re BTs: most turn-based games are going to have such a complex potential solution space that BTs will break under the weight

 

You need something that will evaluate your potential actions in a reasonable, yet tunable way... enter utility systems.




#5169665 Adding some variation to AI

Posted by IADaveMark on 27 July 2014 - 11:57 PM

The simplest answer is what Lithander mentioned. By including random delays, you accelerate the chaos theory that Jeffery is getting at (that little difference will eventually expand into bigger ones). The other thing to do is weighted randoms where, after scoring actions or doing whatever it is you do to select, you pick from the top N actions either completely at random or by weighting them according to their score.

Dude... you just need to stop. Seriously.

Fail.

 

You could have "started a discussion" without 90% of your post being about your stuff.




#5156954 Human-like Chess AI

Posted by IADaveMark on 30 May 2014 - 08:55 AM

Don't think of it in terms of "adding random blunders" and instead think of it in terms of "allowing sub-optimal moves". Humans are rarely perfectly rational or optimal. By including things such as weighted random selection (not random... weighted random that still biases towards the better moves) you allow for "reasonable" moves without always being purely optimal ones.




#5146640 [Flocking] Avoid many "sub-flocks" in Cohesion

It's pretty much mathematically provable that over time, your flocks will break into groups that are proportional to some degree with your k value. It's self-reinforcing. 

 

One method is to not use a hard-cap on k -- but rather use all neighbors within distance d. It's a subtle difference, but I think it would help.

OMG... this is still going on...

 

As for comparing calculation speed, go look up NP-Hard. Humans do better on NP-Hard problems because we get close enough. We estimate and parse to a point. We don't try to solve the optimal solution to the problem like a computer would tend to algorithmicaly do.

 

We also understand the concept of futility... we simply give up after a while.

 

Well... at least people not in this thread do.

I just scrolled through this thread and, after seeing the amount of derpage in it, I think the OP may be on to something. Perhaps computers can equal the intelligence of SOME people in a few years, but certainly not MOST people.

Posted by IADaveMark on 27 December 2013 - 12:09 PM

Is the point of this exercise to create the best player or to use neural networks? Those 2 aren't necessarily the same.

This sounds suspiciously like homework... which is against the GDNet forum rules.




#5111830 How hard is AI

Posted by IADaveMark on 25 November 2013 - 08:03 AM

AI is as hard as how hard you make your AI.
