🤔 I love the "Network Flows" book by Ahuja, Magnanti, and Orlin, but I have to admit that 1993 is looking a little dated. Are there more up-to-date references on network optimization #orms folks would recommend, or is this one still the best?

I recorded a fun video for my coworkers at @getnextmv the other day experimenting with Github Copilot🤖 to solve a knapsack problem using integer programming. It was pretty mind blowing🤯. Anyone else using Copilot for operations research work? youtu.be/bqdJhJ12PT4 #orms

After more than 20 years, I have shut down my repository of Traveling Tournament instances and solution values (mat.tepper.cmu.edu/TOURN). The group at RobinX sportscheduling.ugent.be/RobinX/index.p… has taken it over, and does it a much more appealing way (read: not 1999 hand-coded HTML). #orms
