Computers can rage quit! How cool is that?

This is pretty amazing stuff, I wonder if it's possible to extend this so the program only reads in screen data rather than looking at the RAM.

Mario is so linear that you can just repeat exactly what you did last time. It's not that impressive. Humans have fallibility in reflex actions, and computers don't. Chess AI is much more impressive. Or any game that is not linear.

Pretty appropriate War Games quote there:

That's not how this works.

I'm not convinced. That would have to be the end result to win the game. You have to repeat the moves exactly to jump all of the objects. And listening to the video doesn't convince me that the AI designer didn't just use a round about way to get the computer to remember, and repeat moves. A sort of Derren Brown slight of hand.

@Pincho - Did you watch the video? The AI was getting stuck all over the place because it didn't understand how to progress, so he had to change the way it was analysing the data. There is a clear optimum strategy to complete any level of Mario, that's why it is a good game to use for this. This algorithm is doing a very similar thing to chess AI, just think of each level as a different board position, the AI is calculating how to play in the same way.

I noticed that he said there was a bug in it. So that wasn't much of a fix. I think he is just confusing the issue, and that the program just ends up repeating a move until it works. If he wants to prove that it works then pick a game that is not linear. My tank version placed random dots to learn how to collect. If the dots were always in the same places, it would be easy to program. The Karate Kid it just repeated a kick move. Pacman.. the dots are always in the same places.

A treasure map you walk forward ten places, and dig. That's converting sight into moves. I think that the data of the Nintendo is just changing sight into moves. And that is fooling even the programmer.

I'm not too impressed with it being able to play Mario; it's such a linear non-random game all you have to do is learn where to jump, and remember.

Still, the concept sounds cool.
