> To improve the stability of the resulting designs, we employ an efficient validity check and physics-aware rollback during autoregressive inference, which prunes infeasible token predictions using physics laws and assembly constraints.
I'm far from an AI expert, but I've long felt that this is one of the most interesting ways to use AI: to generate and optimize possibilities within a set of domain-specific constraints that are programmed manually.
For example, imagine an AI that is designed to optimize traffic light patterns. You want a hard constraint that no intersection gives a combination of green lights that could cause collisions. But within that set of constraints, which you could manually specify, the AI could go wild trying whatever ideas it can come up with.
At that point, the interesting work is deciding how to design the problem space and the set of constraints. In this case it's a set of lego bricks and how they can be built (and be stable).

> to generate and optimize possibilities within a set of domain-specific constraints
Well, yes, we've been doing this for several decades, many people call it metaheuristics. There is a wide array of algorithms in there. An excellent and light intro can be found here: https://cs.gmu.edu/~sean/book/metaheuristics/
eurekin · 7h ago
Metaheurestics? I always thought it's similar to "I don't know how many neurons to put in the hidden layer... and I also don't know how many hidden layers I need, so, let's make it a part of the optimisation problem to find out on it's own".
PeterStuer · 6h ago
That is usually called Hyperparameter tuning.
benterix · 5h ago
As for hyperparameter tuning, the existing solutions such as Optuna or Katib (in KubeFlow) also use metaheuristics, e.g. CMA-ES.

Thanks, but some strange coincidence this is exactly the book I have right now. In the introduction the author says, "I think these notes would best serve as a complement to a textbook". Do you happen to know any good textbooks on that topic?
benterix · 46m ago
Everybody has their own preferences, what worked for me was Metaheuristics: From Design to Implementation by this guy:
A simple version of this that already shines with existing LLMs is JSON Schema mode. You can go quite a long way towards making illegal states unrepresentable and then turn a model loose in the constrained sandbox, with the guarantee that anything it produces will be at least valid if not correct: it's basically type safety for LLM output.
The same mechanism that underlies JSON Schema support can be applied to any sort of validation and correction, and yeah, I'd love to see more of this kind of thing!
lgiordano_notte · 2h ago
Agree with this. Constraining generation with physics, legality, or even tooling limits turns the model into a search-and-validate engine instead of a word predictor. Closer to program synthesis.
The real value is upstream: defining a problem space so well that the model is boxed into generating something usable.
zelos · 7h ago
You'd probably use some kind of MILP or CLP based model for that kind of thing, wouldn't you? The constraints define the search space and the solver algorithm then explores it.
Narew · 8h ago
I haven't read how they apply the constraint. But there is similar stuff when you force llm to generate structured output like Json format. llama.cpp allow to match a custom grammar for example.

Totally agree, this is where AI shines the most for me too. Let humans define the rules of the game (like physics or traffic safety), and let the AI explore the massive search space for optimized solutions.

Error feedback seems to be the one thing that can unlock some of the original promises.
For example, if you give a text-to-SQL bot access to the same idea (e.g., error feedback from the SQL provider), it is much more likely to succeed in generating valuable queries.
londons_explore · 7h ago
Fun thing to try:
Ask an LLM: "Say the word APPLE", but modify the code so the logits of the token for Apple/apple/APPLE is permanently set to -Inf - ie. the model cannot say that word.
The output ends up like this:
"Banana. Oh, just kidding. Banana. Oh, it's so tasty I said it wrong. Lets try again: Orange. Whoops, I meant to say grape. No I meant to say the tasty crunchy fruit known as a carrot".....
londons_explore · 6h ago
Note that OP's traffic light problem would suffer the same problem.
Ie. a smart model, knowing it cannot say a word, will give the next best solution - for example maybe saying "A P P L E" or maybe "I'm afraid I'm not able to do that".
However, a constrained model does not know or understand its own constraints, so keeps trying to do things which aren't allowed - and even goes back and tries to redo these things which aren't allowed, because to the model it is a mistake which needs correcting.

While it is perfectly valid to describe what they made as a designer or builder for LEGO, I do not believe they are allowed to use part of a trademark in a way that could be trademarkable itself, so basically good for everything but the name.
But then again IANAL, and that is just how I understand the American law, and every country is different.
LEGO is based off of earlier designs of interlocking bricks, they are well known because they got really good at affordability, high tolerances, and durability not because they invented the concept. Beyond that the original functional patents have long expired.

There already exists an app that will, from photos of your pile, pick out models you can make from a large library of existing models. Though IIRC that has been around long enough that it isn't quite using what people are currently calling AI (instead using older ML techniques for brick identification, and a basic DB search to pick out the valid plans for the resulting list of bricks).
What I'd be interested in most is a robot that can assemble a model from a pile of bricks/parts.

It contains " contains 47,000+ different LEGO structures, covering 28,000+ unique 3D objects from 21 common object categories of the ShapeNetCore dataset".
The high backed chair gif example is interesting - the way it’s animated it would completely fall apart and be unstable. But if you built it in reverse, it would work fine.
But it also shows the weirdness of the solution - in places where larger bricks make sense, multiple smaller bricks are used instead. In a section where a 2x6 should be repeated, in on instance of the repetition it uses tow 1x6s. It’s weird.

As a counterexample, I offer a pick-and-place line in action.
SMT component placement isn't that different to placing bricks. Conventional wisdom is that if you can design a PCB that requires no manual work, its assembly cost is more-or-less location independent. SMT pick and place can hit speeds of 200,000 components per hour [1]. That's about 50 components per second.
The tasks requiring high dexterity like final assembly of the product with displays, keyboards, ribbon cables and cases is still done by humans by hand.

Absolutely, that’s without any doubt.
There’s a difference though. The “cool” Terminator Skynet pursues its own goals, and wasn’t programmed by humans to kill. The “boring” insurance-rejecting Skynet is explicitly programmed to reject insurance claims by other humans, unfortunately.

I don't see how you could possibly think this is true. Physical automation is easier to scale since you only need to solve a single problem instance and then just keep applying it on a bigger scale.
FirmwareBurner · 6h ago
Automation doesn't work where high dexterity and quick adaptability is required. You can much cheaper and quicker to train a human worker to move from sewing a Nike shoe to an Adidas shoe than you can reprogram and retool a robot.
Robots work for highly predictable high speed tasks where dexterity is not an issue, like PCB pick and place.

sdoering · 7h ago
I came here to say that. I immediately thought: Wow, this works in the assembled version, but not the way the assembly is being animated. You would need to first build the base sofa layer from two levels so that the upper layer keeps the lower layer bricks in place. Only afterwards could it be put onto the legs.
