Procedural Map Generation

Im looking to generate maps and rooms. Anyone have any examples or example caps to test it out and see if i can use or suggestions on where to look for guides or examples.

Im working on a game where the game content is mostly randomly generated such as enemies and maps. I want to learn how to make it semi intelligent to do it with some logic. Any suggestions would help. thanks

not a real map with rooms, but looks similar

Here is a site that I have recently found:

It should have something to help you. I haven't had a chance to look through very much of it yet, but there is a large amount of info there or pointed to from there.
