A Learning AI

Because I got no posts over in the Artificial Intellegence forum, which looks like it has been quite a while since the last post, ill repost my thread here....

Im trying to Create for Rise of Civilization a AI that learns from its prior mistakes and improves from them. Im working on ways for this to work out well, and was wondering how everyone else would go about this.

I would Have many different difficulties just in case someone wouldnt like the Idea of a learning AI, like easy, hard, etc. then would have Learning AI. The Ai every match would record it down in a text file, like its resources, Man count, etc. and the same with the players. it would then analyse the 2 files and would write another file based on the stats from the match, like it would make more houses, or Centuries, or etc... then the next match it would use the file it created to try and win. it would eventually beat the player with ease until the player changes strategy.

But, the AI would need to be preprogrammed with the rules and only the rules. then I would make out a 1st battle for it. it would then improve from that point.

give me thought on what everyone thinks...
