found an IRL linear program, took some pictures

4 photos showing the same thing from different angles. a convex polyhedron made of glass, with black edges, is held in two hands. the hands wear white gloves, the polyhedron is wider than it is tall or deep. width is around 4 hands, other dimensions are about one and a half. inside the polyhedron is a orange ping pong ball, and is has found its resting spot at the bottom vertex. hence it solves the LP of minimizing height subject to being inside the polyhedron

wait that actually makes sense. the next largest float64 number after 1e22 is like 1e6 higher, which is way more than 2pi. no use in talking about forward or backward error

Computer Science is no longer just about building systems or proving theorems--it's about observation and experiments.

In my latest blog post, I argue it’s time we had our own "Econometrics," a discipline devoted to empirical rigor.

Just learned that cryptographers are a lot more creative than the rest of us with their videos. Sharing my three favorites:

‘Our children are wasting away before our eyes’: starvation deaths on the rise in Gaza as famine continues

As aid trickles into Gaza, famine-related deaths keep rising. The Gaza Health Ministry warns that “mass death” will soon be seen among infants, as mothers feed them “water instead of baby formula.”

Some news about active set methods.

Sophie Huiberts @sophie.huiberts.me · 9d

SODA notifications are in the inboxes, and this paper will be in the conference :)

This is my second paper using extended formulations to prove running time lower bounds. I am surprised that people have been sleeping on this angle, but happy to fill in the gap where needed

An unconditional lower bound for the active-set method in convex quadratic maximization

We prove that the active-set method needs an exponential number of iterations in the worst-case to maximize a convex quadratic function subject to linear constraints, regardless of the pivot rule used...

(to be honest, Nils and Yann did most of the work during those weeks)

Sophie Huiberts @sophie.huiberts.me · 9d

The paper came from a lucky get-together. Nils and Yann had a problem without solution, Eleon and I had a construction without a purpose. Together we had a 3 week paper writing session

My forthcoming book is already appearing as a "Hot New Release" on Amazon (race relations section) and I AM TRYING NOT TO FREAK OUT. It doesn't actually release until May! I wrote this optimistic and broadly accessible book for you and hope you will consider pre-ordering.*
