Code Search with GPT-4 bloop is a fast code-search engine that leverages LLM QA capabilities to answer questions about code in a conversational way. This is a really neat application of GPT-4. github.com/bloopAI/bloop

SAM intends to minimize worst-direction sharpness but implements a computationally efficient variant. Which notion of sharpness does it minimize? And how? We characterize the implicit bias of full-batch and stochastic SAM. arxiv.org/abs/2211.05729 (1/5)

Interesting MINLP development: @Octeract_UK just made a performance jump and now leads the nonconvex MINLP benchmark of Hans Mittelmann. SCIP 8 is very close though and more than 20% faster than BARON: plato.asu.edu/ftp/minlp.html #orms #scipopt

If you have a rope long enough to wrap around the entire circumference of the globe, the rope is 40,075 km long. If you want to lengthen the rope so that it can hover 1 meter off the ground at all points on Earth, it takes just 6.28 meters more of rope buff.ly/3mQo0UK

Our algorithm ranked 1st on 1 out of three industrial data sets in the #GOCompetition #orms. Our secret sauce: Combining #Optimization, #ML and Physics-based heuristics and being inspired by this quote form by @mluebbecke: "Anything you do, I can do better".

Maurice Queyranne talks about Egon’s classic 1985 polyhedral study of the machine scheduling problem. In my first semester at the @teppercmu PhD, it was a jaw-dropping moment when I finally understood why the linear relaxation of continuous-time formulations is so weak! #orms
