What are the optimization networks? Where can I find info?

So, i recently found this term related somehow to neural networks, but I don't find anymore info on this topic, and it seems interesting.

Does anybody know where I can find more info for starters on this?

thanks in advance

From stackoverflow

• Machine learning algorithms/techniques can be used to optimize solutions to given problems.
  Is that what you are looking for?
  
  I recommend you to buy the book Programming Collective Intelligence: Building Smart Web 2.0 Applications.
  
  You won't regret it ;-)

• Even though I'm not sure what you mean by optimization networks, I'm suggesting you Stuart Russel and Peter Norvig's "Artificial Intelligence: A Modern Approach", which is sort of a standard book in AI.

  I can't find the most recent version(2009) on Amazon though - they are only listing the rather old but not outdated 2nd edition.
