P=NP in the New York Times

The New York Times has a nice article on the recent Communications of the ACM article on P=NP (article at author Lance Fortnow’s site). I had read Fortnow’s article last month, and really liked it. In fact, I am surprised I didn’t blog it: I guess I was too busy worrying about false proofs of […]

Operations Research is Taking Over the World

I often have postings that so-and-so from the world of operations research has become a dean or a provost or even a university president. Somewhat more rarely, I can talk about an operations researcher as a baseball player. Operations Research can lead to lots of jobs. It can even lead to becoming Prime Minister of […]

Data Mining and the Stock Market

As I have mentioned a number of times, I teach data mining to the MBA students here at the Tepper School.  It is a popular course, with something like 60% of our students taking it before graduating.   I offer an operations research view of data mining:  here are the algorithms, here are the assumptions, here […]

Three City Traveling Salesman Problem Solved by Bacteria!

A Guardian (London) article has the provocative title “Bacteria make computers look like pocket calculators” (thanks Hamish for the pointer). They report on how bacteria can be used to search through feasible solutions to the traveling salesman problem to find optimal solutions: The research, published today in the Journal of Biological Engineering, proves that bacteria […]

Pittsburgh: Hotbed of Operations Research and Baseball

Pittsburgh is becoming the center of the universe when it comes to combining baseball with operations research.  First, there is … well, me! … a Professor of Operations Research whose company provides Major League Baseball with their player and umpire schedules.  And, beginning last year, Pittsburgh has had Ross Ohlendorf, who has converted his Princeton […]

Punk Rock OR Blogger Addresses Aviation Security

Laura McLay, author of Punk Rock Operations Research, has an interesting research paper out on identifying risky airline passengers in order to increase security for them. It is costly (both in money and in passenger inconvenience) to subject everyone to the highest level of screening. So who should be screened, given limited screening resources? Laura […]

Brenda Dietrich “Most Creative”

Fast Company has IBM Vice President, Business Analytics and Mathematical Sciences, Brenda Dietrich as number 27 on their list of “100 Most Creative People in Business”.    Nice quote from her: “Mathematics,” says Brenda L. Dietrich, 49, “is not mechanical. You’re finding how things look different on the surface and then seeing what they have in […]

Whither Data Mining?

The New York Times Magazine this week is a special issue on debt (a topic that has a particular resonance to me:  we are still paying off an expensive, but spectacular, year in New Zealand!).   There is a fascinating article on what credit card companies can learn about you based on your spending.   For instance, […]

Much more on the NCAA Tournament

In the hyper-competitive world of operations research blogging, needing to teach a class can put you hopelessly behind.  The Blog-OR-sphere is abuzz with pointers to the CNN article on computer models for predicting success in the upcoming NCAA tournament featuring Joel Sokol (see the video here).  See the blog entry at Punk Rock Operations Research […]

Back at the IMA

I am at the Institute for Mathematics and its Applications at the University of Minnesota.  This brings back very fond memories.  I was a postdoc here 21 years ago at the start of my career when they had a Special Year on Applied Combinatorics.  As I recall there were 10 postdocs that year:  nine combinatorialists […]
