Journalists Should Be Required to Pass an Exam on Conditional Probability

There is nothing more grating than having a journalist toss around numbers showing no understanding of conditional probability (actually, there are 12 more grating things, but this ranks right up there).  In a nice story from NBC Chicago, journalists Dick Johnson and Andrew Greiner write about an autistic teen who has picked the first two […]

Update on LRMC after first round

Sokol and teams’ Logistic Regression/Markov Chain approach had a pretty good first round in the NCAA tournament.  It correctly picked 24 of the 32 games.  On the plus side, it picked the following upsets (NCAA seeds in parens): Northern Iowa (9) over UNLV (8), Georgia Tech (10) over Oklahoma State (7), Murray State (13) over […]

March Madness and Operations Research, 2010 Edition

Normally I do a long post on operations research and predicting the NCAA tournament.  I did so in 2009, 2008, 2007 and even in 2006 (when I think I made blog entries with an IBM selectric typewriter).   This year, I will cede the ground to Laura McLay of Punk Rock Operations Research, who has a […]

Nurse, Nurse! Where’s my Nurse?

I am a sucker for competitions.  The people at PATAT (a conference series Practice and Theory of Automated Timetabling; I was co-chair for their 2004 conference, and a member of their steering committee for a few years) do a really good job at timetabling competitions.  I really liked their competition for the 2008 conference on […]

Sad News on the Netflix Prize

The followup to the wildly successful Netflix Prize has been canceled due to privacy concerns.  From a blog post by Neil Hunt, Chief Product Officer for Netflix: In the past few months, the Federal Trade Commission (FTC) asked us how a Netflix Prize sequel might affect Netflix members’ privacy, and a lawsuit was filed by […]

Google Maps API Enhancements

Google just announced some enhancements to their Directions in Maps API.  One addition, “avoiding tolls and highways” doesn’t really affect me much:  we have only one toll road in the area, and it is pretty well needed to go either east or west.  But the other two are exciting! First, the API now adds bicycle […]

Great Book on Integer Programming

I just received the book “50 Years of Integer Programming 1958-2008”  published by Springer and edited by the blue-ribbon group of  Michael Jünger, Thomas Liebling, Denis Naddef, George Nemhauser, William Pulleyblank, Gerhard Reinelt, Giovanni Rinaldi, and Laurence Wolsey (full disclosure:  I received a complimentary copy, presumably hoping I would post something entitled “Great Book on […]

Summer Internship at Solver Foundation

I get a fair number of emails of the sort “I am studying at ….and I would like to work under your supervision as a summer intern”.  Most of the time they go on to say things like “I want to work under your supervision on stochastic optimization, supply chains, e-commerce” or an of a […]

David Johnson to Receive Knuth Prize

AT&T Labs researcher David Johnson will receive this year’s Knuth Prize from the ACM “for his contributions to theoretical and experimental analysis of algorithms”.  While Johnson is best known for his NP-Completeness book with Michael Garey, he has had an extraordinarily influential career in both the theory of approximation algorithms and in research on experimental […]
