Why isn’t the optimal solution of my MILP model something else?

Anton Korikov talks about finding the closest objective function that would result in the user’s expectations matching how the optimal solution should look like (a counterfactual) — #cpaior2023 best paper award!

Mind blowing start for the second day of #mip2023 with @SophieHuiberts talking about the unacknowledged contribution of women and people from minoritized groups to the solution of the first linear programming problem as computers of the Mathematical Tables Project #orms

[Kareem Carr, Ph.D. @kareem_carr]

WHY do we divide by n-1 when computing the sample variance?

I've never seen this way of explaining this concept anywhere else.

Read on if you want a completely new way of looking at this.

In case you missed @CalvinTsay's tweet, we have just released a survey along with @gmunoz_m and Joey Huchette on polyhedral theory in deep learning: https://t.co/W0Y2kdcIFe

This thread covers the main points, why we did this, and why you should care about it. Read along!
