The day started off with an encore presentation by the edelman winner - Indeval. Interesting talk. The theoretical stuff was not particularly interesting, but the fact that they got some OR stuff to work in real time in a mission-critical system, and involving billions of dollars is really cool. Next, i managed to attend a couple of optimization-focused talks on Approximate Dynamic Programming at Schneider Trucking, followed by 'the practice of the alternative' by Dr. Jeffrey Camm from the U of Cincinatti. He is from the Brown-Rosenthal school of practical OR, which i heartily subscribe to as well, and it was probably the most informative talk of the meet for me.
The rest of the day was devoted to the energy industry. We had another plenary by Richard O'Neill, Chief Economic Advisor to the Fed Energy Regulatory Commission. This guy went into some depth on electrical circuits and mixed integer programs. Quite unexpected, but it was great for us optimization practitioners. Then I got to listen to more presentations on energy-related topics including analytics for the smart-grid.
All in all, it was an enjoyable conference, even if one can attend only 10-12 of the 80 presentations on offer. Great location, excellent hotel service. Good job, Informs!
