Part of my work at Standard Form (https://heystandard.com) is to build physician schedules that resemble the classic "Nurse Scheduling Problem" in operations research (OP). We could implement this without AI at all with many open-source algorithms like OP-Tools and Gurobi, but our customers are physicians who cannot code and neither do we have time coding each solution for each customer. So, we're venturing into having LLMs program such optimizers from human natural language.

The state-of-the-art has been to do fine-tuning on OP-tool datasets. The problem is that very, very few datasets cover scheduling problems and a slither of those that exist don't realistically represent actual scheduling constraints.

Another method is to do multiple prompting strategies, like OptiMUS, which is the one I've been prototyping with. It's inconsistent with GPT-5, and any lesser models will fail to model the problem correctly at all and produce solvers that are infeasible (but in fact are) or just error.

I'd like to think that this is actually a solved problem, since it comes down to teaching LLM how to code, and we're not asking LLM to output schedules generatively. However, the literature is sparse on this topic and all the attention right now goes to LLMs doing the actual maths, which I think is only experimental at this time.

Operations research is one of the unclaimed corners of AI and would love any input from those who have expertise in OP and/or AI. This is something we believe will be an important aspect of how the world's industrial output will rely on, and we ought not to let this be in the backburner as many (and I mean many) people are still doing scheduling manually on Excel or even paper and post-its.

Any input appreciated.

I’m thinking of developing multiplayer experience on my app, where multiple users can modify a shared ‘whiteboard’ in real time. I’m aware that there are companies creating multiplayer experiences on top of their existing product (Figma, CodeSandbox), and some that have it from the beginning (Observable for example). So, I know it can be done no matter what stage the product is at. However, there’s not many online resources on how it can be done (and how hard), besides a nice article from Figma (https://www.figma.com/blog/how-figmas-multiplayer-technology-works/) and fairly theoretical literature on Conflict-free Replicated Data Types (CRDT).

Do you have any experience building such a feature? Where should I begin? What would you recommend?

For context I’m a full-stack engineer and have used React Typescript and a couple of backend tech (Java, Go). Thank you :)
