It wouldn't be a SMB speedrun video if it didn't have the bus analogy.

Jokes aside, Summoning Salt is a great Youtube channel, and it makes me feel emotionally invested in speedruns of games I've never heard of before. Great storytelling. Not to mention that speedruns (and the glitches people find to get world record times) are pretty interesting from a computer science standpoint.

Speedrunning is the only sport that I am excited about.

It‘s probably way too late to change the rules now, but even though it‘s totally legal according to the rules on the leaderboards, using a keyboard seems like quite a difference from using a controller, and from the end of the video, sounds like it does make certain moves easier.

as someone with no prior opinion or interest in speed-running, this is a surprisingly good watch!

some thoughts

- given the timeline of progress, i guess we might see THE perfect run in the next 12 months or so

- how did they figure out the theoretical best time in the first place?

- is machine learning being applied to this problem yet? might be able to discover some more time saves

They don't know the theoretical best time but they know what is possible using tool-assisted speedruns (TAS) using the current set of known tricks. So it's possible there are still tricks to discover that will improve the speed floor, but it's been a long time since anything new was found.

> how did they figure out the theoretical best time in the first place

A rarely used tool is brute-force searching for ideal inputs by making a computer play the game, trying all possible inputs. In theory, this process could find the ideal set of inputs for any game, but since the space of all possible inputs grows exponentially with the length of the sequence, this is only viable for optimizing very small portions of the speed run. Instead, a heuristic algorithm can be used. Although such an approach does not guarantee a perfect solution, it can prove very effective for solving simple puzzle games.
