Metal Trees


Roxy Paine’s sculpture “Defunct” (photo, Nicole Marti) There were a couple of seminars today and one mentioned a result giving the following interesting corollary. Suppose we have a graph , and with each edge e we associate three numbers which we interpret in the following way: to construct edge e we need to use kilograms […]

Three weeks ago I went back to Canada to accompany my high school on their trip to the American Computer Science League finals. Both of the teams did very well and it was a pleasure to be involved with such bright kids, not to mention the trip was a great opportunity to catch up on […]

I defended my PhD thesis one week ago! (Successfully!) Although I am not finished until I complete my thesis revisions, being past the most stressful 2 hours is excellent and I enjoyed getting to see some talks from visitors on the same day. Other epic wins: I got to visit Pittsburgh’s Carnegie Mellon University 2 […]

Schrijver is best known (I think) for his work in combinatorial optimization (including a 3-book series that spans the whole discipline) […]

My department, Combinatorics and Optimization, is hosting a conference this week in honour of its 40th anniversary. So things are about to get a little more nerdy on this blog as I will be mentioning some of the talk details. For today, at least: a picture! (click for big-ass pdf) It’s my contribution for today’s […]
