Random Session Report for Sunday

by Walt DeGrange on October 15th, 2012
Here is a link back to my Random Session Post.
Unique secret location on the third floor of the Hyatt. Kind of like Shangri-La although I didn’t stay long enough to figure out if I stopped aging. Below is a picture of the courtyard outside the conference room.
Small cozy conference room. Four briefs so this session was action packed from the get-go.
  • Presentations were done on a German ThinkPad. Evidently the keyboard is a little different.
  • Alternate ways to perform Benders Decomposition. “I don’t know about you but I am always on the lookout for alternate ways to perform Benders Decomposition.” And my wife tells me that OR doesn’t produce any good cocktail party lines.
  • ZIMPL 3.3 – Open Source Modeling Language for solving MIP and NPL. The example code solves a Sudoku puzzle. Now that is useful! And of course the price is right.
  • APMontitor Modeling Language – Uses servers not client software. Accessed through MATLAB, Python, Web Interface. Used with applications that require resolving problems every 2 seconds. the fastest application required reoptimization every 0.1 seconds. Makes waiting hours for my master thesis model to run so ten years ago.
Monday’s random session is Track 62 – Auctions 1:30-3:00PM
