Super Mario, Doom will become harder to master thanks to AI
Researchers have trained AI to create newer game levels so saving Princess Peach will become a much harder job.

Outside of the office, she can be found binging on Korean variety shows, if not chilling out with a book at a café recommended by a friend.
First, the machines beat us at Go. Now, they're making games harder for us.
In two separate papers, researchers have developed artificially intelligent models -- namely generative adversarial networks -- to build new game levels for Super Mario Bros and Doom. And with the addition of another tool, researchers found level generation for Super Mario is "further improved."
GANS are a form of AI used in unsupervised machine learning. Two neural networks -- the "generator" and the "discriminator" -- are pitted against each other so the generator learns better ways to fool the discriminator, which (of course) tries not to be tricked.
"Level design usually heavily relies on domain expertise, good practices, and an extensive play testing," researchers wrote in the Doom paper.
"To deal with these issues, several game researchers [spent] considerable effort on studying and designing procedural content generation systems that, exploiting machine learning and search algorithms, can model the level design process and assist [the] human designer," they added.
This particular form of AI has also been said to threaten lawyers' and poets' jobs, although we're not sure how serious that threat is. It's not doing well in fashion design yet, for example.
It's not the first time people have tried applying GAN to games either. Programmers at Maverick Games published results on news site Gamasutra in February pertaining to their experience using GAN to create new game levels for an RPG called Fantasy Raiders.
Despite limitations -- researchers found GANs had occasional problems that resulted in broken structures -- the programmers agree with the researchers writing in the Doom paper that GANs are a "promising approach to level generation."
The AI-generated levels aren't yet available on Doom and Super Mario as the projects are still prototypes. There's no telling when they could become available though, so enjoy the games while they're still easy enough to play.
