New week, a new blog post about optimization. This time about a new modeling framework in Python called "pyOptInterface". Is it any good? Where does it fall short? Let's find out!

pyOptInterface - what can it do? - Richard Oberdieck
pyOptInterface just turned 1 year old, and I finally had an opportunity to take it for a spin. Let's have a look!

Been a long time, but better late than never they say. Here is a short new blog post about #pydantic, which does not always do what it says it does.

Work in optimization or operations research? Are in Copenhagen on Thursday? Then you might like this tutorial on "Testing Optimization Code":
www.dorsnet.dk/events-1/dor...
We'll do a deep dive on what it means to test .... optimization code (surprised pikachu face :) ). And there will be cake :)

This job post from @gurobioptimization.bsky.social just popped up for me: A "Gurobi Development Scholar", who will go through a 2-year period to become a Gurobi developer. The only plausible explanation for this is that apparently they cannot find existing MIP devs but have to train them? Really??

This is a really fun read: jordanbryan.substack.com/p/on-buildin...

On Building Git for Lawyers
Over this past weekend, Twitter discovered the problem that I have dedicated the past four years of my life to solving. Why don't lawyers and other non-coders use git?

A new blog post! This time about LLMs in optimization:

This is the first time I am writing something a bit longer, so please let me know what you think. I was seriously considering splitting this into three parts, but hey, maybe someone enjoys this :)

So I've seen the #Gurobi Gurobot GPT, and I've seen the launch video of #Quantagonia for their DecisionAI. Is there any other LLM-based initiative in the OR space that I am not aware of?
