Perfect showcase that for this type of problems using an LLM to search over the space of algorithms instead of smartly searching over the solution space is a complete waste of resources.

I’m shocked that in times academic institutions get attacked by governments, INFORMS launches a 15 min commercial podcast for Amazon, whose CEO allied with Trump recently. None of the discussed research is public, what’s the benefit for the #orms community? resoundinglyhuman.com/episodes/202...

This is like watching all the animals fleeing inland right before a tsunami. They know what's coming. So did Einstein in 1932 when he left. Doctors Stanley and Snyder are two of the top experts on authoritarianism, and have called it quits. I'll be joining them in Canada this summer.

New preprint with @jannisku.bsky.social! We look at objective-robust optimization under the oracle model, and connect most approaches from the literature under a Frank-Wolfe algorithm. The additional spice is Nesterov smoothing which is particularly effective when the uncertainty budget is large.
