COIN-OR is a project to spur open-source activities in operations research. I am a big supporter of this activity, to the extent that I was part of its Strategic Leadership Board for a term until I did them an even bigger favor by stepping aside for people who could be even better at this than I (not that such people were exactly rare: my time on SLB corresponded to a somewhat over-committed time for me).
Every year COIN-OR gives out an award called the COIN-OR INFORMS Cup. This year’s winner has just been announced, and I think the committee has made an inspired choice:
The submission “OpenSolver: Open Source Optimisation for Excel using COIN-OR”, by Andrew Mason and Iain Dunning, has been selected as the winner of the 2011 edition of the COIN-OR INFORMS Cup. OpenSolver is an “Open Source linear and integer optimizer for Microsoft Excel. OpenSolver is an Excel VBA add-in that extends Excel’s built-in Solver with a more powerful Linear Programming solver.” (from http://opensolver.org)
This year’s award recognizes that lots and lots of people want to use top-notch optimization code, but would like to stay in the world of Excel. The authors of this work (who I am very proud to say come from the University of Auckland (at least in Andrew’s case), where I was a visitor in 2007) have done a great job in integrated the optimization codes from COIN-OR into an easy-to-use interface in Excel. It is a fantastic piece of work (that I blogged about previously) and one that I believe does a tremendous amount of good for the world of operations research. If you can model in Excel’s Solver, then you can plug in OpenSolver and start using the COIN-OR solvers with no limits on problem size. I am also delighted to see that that they have moved to CPL licensing, rather than GPL, which was my only whine in my original post.
Congratulations Andrew and Iain. If you would like to celebrate this award, there is a reception to attend, thanks to IBM:
