The researchers started by sketching out the problem they wanted to solve in Python, a popular programming language. But they left out the lines in the program that would specify how to solve it. That is where FunSearch comes in. It gets Codey to fill in the blanks—in effect, to suggest code that will solve the problem.
A second algorithm then checks and scores what Codey comes up with. The best suggestions—even if not yet correct—are saved and given back to Codey, which tries to complete the program again. “Many will be nonsensical, some will be sensible, and a few will be truly inspired,” says Kohli. “You take those truly inspired ones and you say, ‘Okay, take these ones and repeat.’”
After a couple of million suggestions and a few dozen repetitions of the overall process—which took a few days—FunSearch was able to come up with code that produced a correct and previously unknown solution to the cap set problem, which involves finding the largest size of a certain type of set. Imagine plotting dots on graph paper. The cap set problem is like trying to figure out how many dots you can put down without three of them ever forming a straight line.

FunSearch (so called because it searches for mathematical functions, not because it’s fun)
I’m probably not the only one who wondered.
Some people might consider that fun :(
I would have called it FunkSearch, to eliminate this misunderstanding.
The Funk, the Whole Funk, and Nothing but the Funk
Gotta have that funk
So, they basically “intelligently” brute forced it? Still cool.
Isn’t that how we learn too? We stop doing the things that don’t work in favor of things that do while repeatedly “brute forcing” ourselves (training/practice).
it is what we (the people) do as well. we look at the data and try to find a pattern. but the computer can process larger amount of data than people can.that’s it.
no. your claim sounds ridiculous.
I didn’t claim anything. I asked. If I’m misguided, then so be it, I’ll learn somthin’.
Well don’t be a poopy pants!
It’s not brute forcing though. It is similar to genetic programming, it seems, but with more less understood parts.
I mean, I would also call genetic algorithms a form of brute forcing. And just like with genetic algorithms, this approach is going to be severely limited by the range of values that can be updated and the ability to test the outcome.
Why would you not be able to test the outcome fully? And what do you mean by “limited by the range of values that can be updated”?
So they configured the experiment so that only certain lines of code were able to be iterared/updated. Maybe you could ask it to start from scratch, but I imagine that would increase the time for it to converge (if it ever does).
Regarding testing, not all mathematical proofs can be verified by example. Here they were trying to prove that there was an even lower bound for the problem, but not all proofs will work with that structure.
Buried the fucking lede with misleading garbage. They came up with new, larger cap sets than were previously known. That’s cool, but it doesn’t actually prove anything related to open cap set conjectures. I’d contend this is similar to the early solutions of the four-color map theorem albeit built with a computer coming up with the models to brute force. Pretty fucking neat; not solving an unsolvable problem by any stretch of the imagination. I would expect that kind of hyperbole from the lay press not the fucking MIT Review.
Edit because this shit is really cool: I intentionally linked this to the four color map theorem because that was the first brute force proof (at least via computer). Lots of people got pissed at the authors and said it was invalid because they reduced their special cases to a finite set and had a computer chug through them. imo proof by computer is valid and one of the ways stuff like this can aid math. There are so many problems in combinatorics alone that could benefit from this treatment of just getting new, unknown special cases to get to a general case or handling previously too large finite sets of special cases.
We have solved the unsolvable problem.
Should probably rename it then.
Lots of problems are unsolvable until they’re solved.
Kind of abusing the word there a bit though eh. Maybe call them something like “really feggin hard problems” instead.
This is mostly incorrect. There are provably unsolvable problems and unsolved problems. Many times someone will mislabel the latter as the former; that doesn’t make it actually provably unsolvable. Often we suspect unsolved problems might be unsolvable but do not go to the extreme of claiming it until it’s proved impossible to solve.
Does this mean computers can finally do floating point math!
“Gold among the garbage” sums up AI very nicely.
This gold… smells… funny…
Guarantee this comes out as untrue. Mark me.
They basically found a more effective way to brute force the problem. I don’t doubt that it’s possible. The title calling it unsolvable is nonsense though.
Does it perform better in a significant way to genetic programming?
This is the best summary I could come up with:
Google DeepMind has used a large language model to crack a famous unsolved problem in pure mathematics.
In a paper published in Nature today, the researchers say it is the first time a large language model has been used to discover a solution to a long-standing scientific puzzle—producing verifiable and valuable new information that did not previously exist.
FunSearch (so called because it searches for mathematical functions, not because it’s fun) continues a streak of discoveries in fundamental math and computer science that DeepMind has made using AI.
Built on top of DeepMind’s game-playing AI AlphaZero, both solved math problems by treating them as if they were puzzles in Go or chess.
It combines a large language model called Codey, a version of Google’s PaLM 2 that is fine-tuned on computer code, with other systems that reject incorrect or nonsensical answers and plug good ones back in.
Terence Tao at the University of California, Los Angeles, who has won many of the top awards in mathematics, including the Fields Medal, called the cap set problem “perhaps my favorite open question” in a 2007 blog post.

Can it divide by zero ?
I thought this was interesting bc it’s an instance where a LLM has done something undeniably novel and unique while expanding human understanding. It’s a chink in the armor of the idea that a LLM is a “stochastic parrot” that can only regurgitate and never create.
I’ve been toying with this idea that LLM are showing us that what we thought of as creativity, learning, and problem solving aren’t as rarefied as we thought. We know that AI isn’t conscious, maybe consciousness isn’t as prerequisite to behaviors and cognition as we thought.
I’m not so sure, it feels a lot more like the https://en.wikipedia.org/wiki/Infinite_monkey_theorem, but with a model helping limit the outputs so they are mostly usable. As is stated in the article, it took millions of runs and couple of days to get the results. So its more like brute forcing with a slightly modified genetic algorithm than anything else.
I didn’t see a link to the full article, so maybe something more creative is happening behind the scenes, but it seems unlikely.
Your interpretation is correct. There’s no new logic here, just new special cases of a problem whose general solution is still unknown. I think it’s pretty cool and has a lot of value in places like design theory where the getting examples to try and play around with general solution ideas is really tough. But all it did was creatively crunch numbers.
This approach sounds more like selective breeding to me.
If you do this with cats and select in each generation until you obtain a particularly fluffy cat, the cat doesn’t get the credit. Nobody says “wow, how smart are cats for achieving this”, they praise the breeder instead.
Which is as it should. The people who seed and select these algorithms and can recognize a breakthrough deserves the credit not the churning machine that goes through millions of permutations blindly.
