It was an honor and a pleasure to chair the 2025 Mixed Integer Programming Workshop from June 2 to 6 in Minneapolis, MN. For everyone that missed it, we missed you too but you may catch up on the talk/poster details and competition winners via mixedinteger.org/2025 and the #mip2025 workshop program.

See you all in Connecticut for #mip2026! Meanwhile, you can play the new version of the cutting plane game here: gonzalomunoz.org/the-cutting-... … or you can start thinking about GPU algorithms for MIP to enter the next Land–Doig Competition!
