I was onsite today watching the contest live, and great atmosphere all around. One surprising outcome: the team in 17th place solved the same number of problems as the team that won gold in 4th place. Hopefully that isn't too demotivating to any team and we can see better separation in the future. After all, it can only mean that the problemsetters underestimated the contestants ;)

Congratulations to all the teams!

The "Diamond Sponsors" of the event are Huawei and OpenAI. I found the welcome note from OpenAI [1] quite curious:

What you take from this week - the sense of being stuck, the thrill of progress, and the practice of building together - will remain critical as you shape your community and the future you build.

Does anyone know how long it will be until the input/output data packet is made available? I'm interested in taking a crack at some of these but know I always miss an edge case.

In the TV show Silicon Valley, there’s a joke that Nelson “Big Head” Bighetti, the perennial underperformer, did his undergrad at ASU. But I guess that’s one thing the show got wrong, because Arizona State University finished among the top three American schools in the world finals.
