I am spending a month in Beijing. This week the China Theory Week is under way, the second in a series of annual events bringing graduate students from all over to Beijing for a week of talking about theory.
In October, there will be the China Symposium on Theoretical Computer Science, which is like the Theory Week but with older people.
Yesterday I spoke about my work on spectral methods for Max Cut, on which there have been a couple of advances since I posted about it here: (i) Moses Charikar has improved my analysis of the recursive algorithm, and (ii) I am now able to handle (in a complicated way and with very poor bounds) the “Max Cut Gain” problem.
I will write about it here, but first I will have to find out how to do it. WordPress is blocked, I have not been following all the explanations about “tunneling” and “proxy servers,” and so far the only way I have found to post here (open a remote desktop on a Berkeley computer) is excruciatingly slow and not conducive to write math (which needs previews etc.). Meanwhile a revised paper is available online.
