The parent of SourceForge.net has decided to become Geeknet, Inc (how much did they have to pay for geek.net, I wonder). I have mixed feelings on this. On one hand, I am trying to learn from Wil Wheaton and embrace my inner geek. I have done this so well that my colleagues tell me my [...]
Just in time for the INFORMS Meeting in San Diego, the Microsoft Solver Foundation folks have announced Solver Foundation Version 2. I am particularly excited about this since I have promised (and have been negligent about) a new course this year entitled “Operations Research Implementations” aimed at our MBA students. The idea is [...]
Version 2.0 of the Gurobi Optimizer has been released. Since it was only about a year ago that I first blogged about Gurobi, it has moved along very quickly. The “horse race” between Gurobi, IBM, and FICO doesn’t have a simple answer, but it is clear that Gurobi is competitive with the other [...]
Hans Mittelmann has some new benchmarks comparing CPLEX 12.1 with GUROBI 1.1.2 on various mixed integer linear programming instances (I last wrote on these benchmarks last January with earlier versions of both codes: be sure to check out the comments from that post since many of those comments apply to this also). He covers both [...]
Two things happened to me last week with regards to IBM/ILOG (a topic I have written about quite a bit):
I was on a conference call with an ILOG person and I said, jokingly, “Is that XXX from ILOG, an IBM Company?”. His reply: “Nope, just XXX from IBM”. The “ILOG, an IBM Company” phrasing ended [...]
Wolfram|Alpha is an interesting service. It is not a search engine per se. If you ask it “What is Operations Research” it draws a blank (*) (mimicking most of the world) and if you ask it “Who is Michael Trick” it returns information on two movies “Michael” and “Trick” (*). But [...]
While Google is, of course, heavily active in analytics, the company has not been known for its operations research. The “ethos” of the company has been heavily computer science based. So, while I would count much of what they do as “operations research”, they probably would not use that label.
The line between operations [...]
I am behind Erwin Kalvelagen, who writes an extremely useful blog where many challenging modeling problems are solved (this is one of my “must read” blogs), in announcing that Gurobi’s standalone software is now available. I particularly like that the trial version is 500 variables and 500 constraints, which is large enough to see how [...]
Over at the INFORMS Practice Conference Blog, I have entries on Gurobi and ILOG, an IBM Company. Both presentations were inspiring in their own ways.
Gurobi Post:
It goes without saying that these statements are my individual views of the workshops, and are not the official word from either the companies or INFORMS.
The world of optimization [...]
IBM announced today that it is forming a new consulting group for business analytics and optimization, called Business Analytics and Optimization Services. With 4000 people, this is a pretty serious operation! You can check out the news release and the Business Week coverage. I’ll pass over the fact that IBM doesn’t use the phrase “operations [...]
