New algorithms for matching problems

A preprint with Jacky Lo, just submitted to arXiv and on my publications page. The paper was ultimately inspired by a Christmas party game, which shows that the line between work and play is hard to draw. Abstract: The standard two-sided and one-sided matching problems, and the closely related school choice problem, have been widely […]

Fair Open Access Principles

I have been working for the last 18 months with a group of talented and committed people to accelerate conversion of subscription journals to open access. There are many barriers, and many pitfalls. For example, so-called “predatory” open access journals that take authors’ money and provide no quality control have gained considerable publicity and must […]

A rant about Lufthansa

Apologies, a rant is required. I just swore at someone on the phone, which is quite a rare occurrence. Read on to see why, if you dare. Lufthansa is by far the worst airline I have ever had the misfortune to deal with (I haven’t flown on anything really unsafe, of course, but have flown […]

What happens to journals that break away?

Although it is still a relatively rare occurrence, several journal boards have broken away from large commercial publishers. A good list is at the Open Access Directory. These journals usually are required to change their name, because the previous publisher will not relinquish it. They are cut off from the enormous support provided by large […]

A blockage cleared

After a very long time, some (revised versions of) papers have emerged, two on distance rationalizability of voting rules with Benjamin Hadjibeyli, one on signed networks with Samin Aref, and one on “wisdom of crowds” with Patrick Girard and Valery Pavlov. There is a long list of things still to do, but this is a […]


I saw a concert version of this tonight with Simon O’Neill in the title role. While the plot is quite weird and distasteful in places, the orchestra and singing were excellent. I saw Simon O’Neill in 1997 (I think) in a small role in the play Master Class in Auckland. He has certainly gone up […]


I attended this biennial meeting for the fourth consecutive time. Attendance in Toulouse was substantially larger than previously. Organization was excellently led by Umberto Grandi. Toulouse was busy with tourists augmented by fans of Euro 2016 football teams and evenings were very noisy downtown. The city seems like a pleasant, slightly provincial place. There were […]

We have met the enemy, part 2: clueless authors

In recent discussions, an editor-in-chief of an Elsevier journal made the assertion that there is no point in going through the hassle of switching to an open access publishing option, because authors are allowed to post the final accepted version (“postprint”) publicly, for example at Ignoring the rather cavalier attitude to readers (what if […]
