[In which I demonstrate my ignorance of stochastic modelling]

Suppose you could assign a single-valued score x to any job, based on how well it suits you. Say, 1/norm(difference between this and your "ideal" job), so the score is infinite for your dream job, and small for things not at all like it.

Suppose a sequence of jobs (or job offers) arrives ( Read more... )

I think today I had a decisive breakthrough in battle with my continuation problem. There's still some mopping-up to do, and an interesting discrepancy, but in principle, things may finally be working. Three ideas led to today's victory:

1. If Y is a function of X (and is monotone, and continuous), then X is a function of Y too. Sometimes, it's easier ( Read more... )

Who Cares About Poincaré?, by Jordan Ellenberg at Slate, contains this gem, from geometer Christina Sormani:

Hey, you've got this alien blob that can ooze its way out of the hold of any lasso you tie around it? Then that blob is just an out-of-shape ball... .[The proof proceeds by] heating the blob up, making it sing, stretching it like hot ( Read more... )

So Oberwolfach might not be quite idyllic, but it's certainly a wonderful place all the same. It's halfway up a narrow valley, surrounded by steep green hills which are heavily wooded at the tops. There are plenty of opportunities for nice long walks in the area, and I should really find time to get out a bit more. There are lots of features about ( Read more... )
