Something that may help you against the AI is to put at least indy strength 6. The AI attacks everybody and you are always fighting a multi front war against them. Try out a game with indy 6 and see if that helps because it makes the AI advance slower. I never really played Ulm much so I will let others give advice on what to do with them. I have been playing multiplayer games for I think a month now and it is nowhere near like playing against the AI.
