Thoughts on the world of operations research
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 two solvers, … Continue reading “Gurobi 2.0 Released”
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 … Continue reading “Bluewashing Complete!”
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 … Continue reading “Further workshops at INFORMS Practice”
I am one of a stable of guest bloggers for the INFORMS Practice Meeting. Rather than double post, I’ll move over to that blog for a few days (unless I have something to say that isn’t appropriate for an INFORMS blog), with pointers from here. My first entry there: Tough Choices!, where I complain about … Continue reading “Blogging for the INFORMS Practice Meeting”
This is the blog’s third birthday! It has been an exciting year, both personally and in the world of operations research. Personally, at this time last year, I was in New Zealand, waiting for the weather to warm up and wanting to get back in the water. Since then, we have returned to the US, … Continue reading “Happy Birthday to the Blog!”
More than 20 years ago, Bob Bixby decided the world needed a better linear programming code. This wasn’t a particularly obvious decision. First, there were already existing linear programming codes. Second, linear programming implementation was not exactly a hot research topic. Third, Bixby was not particularly known in this area. A typical paper for Bixby … Continue reading “Happy Birthday CPLEX”
I had previously written about the exit of Gu, Rothberg, and Bixby from Ilog. I was curious where they would end up: Google, IBM, Yahoo? Somehow, I thought they would be together, but where? That has now been answered. Gurobi Optimization has gone live today. From their page: Gurobi Optimization is in the business of … Continue reading “Gurobi goes live”
William Patry, Google’s Senior Copyright Counsel, is ending his blog “The Patry Copyright Blog“. That sentence, in short, gives one of the two reasons he is ending the blog (the other is the horrid state of copyright law, in his view). Patry is a long time copyright lawyer who started the blog while in private … Continue reading “Personal Blogs, Personal Views”
We are about 6 weeks away from the Pittsburgh INFORMS conference. On the plus side, we have been blessed with outstanding local and global support (ILOG has supported upgraded conference bags, SmartOps has sponsored a new Tuesday reception, IBM Center for Business Optimization has sponsored a new Prize Ceremony and much, much more). On the … Continue reading “Pittsburgh INFORMS information”
