Super Smash Bros. Melee A.I. Good Enough to Beat Some Pros

The artificial intelligence is the brainchild of a team at MIT.

Artificial intelligence is making in-roads into fighting games, with an A.I. from a Massachusetts Institute of Technology team taking on, and beating, professional players in Super Smash Bros. Melee.

A group of programmers from MIT's Computer Science and Artificial Intelligence Laboratory has developed an AI that can go punch-for-punch against globally ranked players. It trained a neural network to play by inputting coordinates of all the gameplay items for various levels, such as players and edges. The A.I. acts as an in-game computer player learning from scratch.

“It uses a combination of human techniques and some odd ones too – both of which benefit from faster-than-human reflexes,” team leader Vlad Firoiu told TechCrunch. “It is sometimes very conservative, being unwilling to attack until it sees there’s a opening. Other times it goes for risky off-stage acrobatics that it turns into quick kills.”

The video below shows the AI playing against several ranked players. The A.I. has a problem using projectiles, and it also can't handle players that avoid combat. “If the opponent crouches in the corner for a long period of time, it freaks out and eventually suicides,” Firiou said.

The team has put out a paper on the project and has been submitted for consideration to an AI conference in Melbourne.

        Because people only play Melee.

        Melee is a lot faster and through some glitches allows for some deep competitive play so people love it. Otherwise it doesn't have as much going for it as the newer versions, or at least Smash 4.

        Melee has been hacked to hell and back, not saying the newer ones haven't but definitely more work has been done on Melee. Also, the pro scene seems to feel Melee has the most depth due to physics glitches so there you have it.
