NL8 Solved!

Almost 10 years ago, Kelly Easton, George  Nemhauser and I created something called the Traveling Tournament Problem.  The name is George’s:  I wanted to call it the Problem where Teams Play a Round Robin and Travel and Stuff, but George’s name is catchier.  The problem came from work we had done with Major League Baseball […]

Data Visualization

I have always loved Data Visualization (well, always since my adviser John Bartholdi pointed me to Tufte’s classic “Visual Display of Quantitative Information”).

Florida International University is planning to shut down 17 degree programs, including industrial and systems engineering. I have good feelings for FIU, since my first doctoral graduate took a position there (in the business school; he has long since moved on), but it is shocking that a popular and important degree such as IE would […]
