I ported Google Or-Tools CP-Sat so you can run it multi-threaded in your browser. Any other of their solvers I should port next?

The idea was to use it for my event planning startup, but that didn't work out anyway, so I decided to open source this work. Getting or-tools to compile as it is a bit difficult, it's not super portable. Getting it to work multi-threaded across new and old browsers took a lot of work, and since my event planning tool never took off, I thought I would open source this part. You should be able to run everywhere, but tell me if it doesn't work. I haven't benchmarked again the original yet, but WASM tends to be 60% the speed of native. The one catch is that the web workers take forever to spin up, so for small tasks it's often run quickest on 1 thread.

Open to thoughts, feedback, ideas!

Computational management?

LLMs are becoming surprisingly strong in analysis, synthesis, and business reasoning.
Are we moving toward truly computational management…
or simply better decision support for human executives?
And is there already an academic field or theoretical framework studying this direction?

INFORMS annual meeting 2026

Hi all, I have a presentation in this meeting this year. They told me to register before July to make sure of my slot. But I don't see the link to registration. Any ideas?

Publication

Hi all,

I’m a final year BSc student working on a scheduling problem for my thesis. The idea is that for my model its complexity is already known, so it’s proven to be polynomial but only through LP machinery arguments. There doesn’t exist a concrete algorithm for it (to the best of my knowledge). I have managed to come up with one and prove its correctness and I was wondering would this be worthy of publication at a serious place like Journal of Scheduling or OR Letters? This is my first time ever doing research and I really really like it but I’m trying to understand the whole publication world and the scope overall.

Any suggestions / questions are welcome!

Thank you

I got tired of RL agents "solving" inventory tasks in 10 minutes so i built a high-fidelity environment that actually breaks them.

I think most supply chain envs use flat demand, instant shipping, and zero noise. You train an agent and it "solves" the the environment instantly but then it just fails the the second it touches real-world volatility.

i spent the the last few months building this logistics suite because i wanted to see if a continuous-control agent could actually handle the the bullwhip effect. my PPO agents kept "starving" at hour 40. I realized I’d accidentally built a starvation trap where the the lead time is 24h but if the the agent tries to stay too lean to save on costs it just cant recover when a route severance spikes lead times to 150h.

I've open-sourced a 5,000-hour sample on hugging face if you want to play with the the telemetry or test some offline RL:https://huggingface.co/datasets/AIMindTeams/defense-logistics-stochastic-simulation

curious to hear how others are handling long-horizon planning when the the failure costs are 400x the the cost of holding inventory. how are you guys tuning your discount factors?
