I was pleasantly surprised this was about the first thing that popped into mind (having played the game a lot as a kid on a Coleco).
I played it on the Apple ][ -- it seemed to be ported to many platforms. But it is a fairly obscure game -- it makes me wonder why they picked it rather than a more common one.
It was picked because it is difficult to train a reinforcement learning model to play it well. In most other games you can create a reward function based on the score or something similar, and then the AI can explore possible actions that gives the best score. In those cases AI players are already doing quite well.
In this case finding the key requires long term planning to get an actual reward and the AI has previously got stuck before that.
A computer that has diarrhea? Now that’s novel.
Also read the source domain differently, subliminally.
