See Laci's and Harald's posts for more technical information.   Laci Babai has posted an update on his graph isomorphism algorithm. While preparing a Bourbaki … Continue reading On exp(exp(sqrt(log n))) algorithms.

Now that the important event of the STOC deadline has passed, we can talk about trivial matters such as the future of the free world (but of course, like a broken record, I will come back to talking about sum of squares by the end of the post). A priori predicting the result of the … Continue reading Post-deadline diversion: Election predictions

As mentioned before on this blog,   STOC 2017 will be part of an expanded “Theory Fest” (http://acm-stoc.org/stoc2017/) which is being planned by a small committee (Sanjeev Arora, Paul Beame, Avrim Blum, and Ryan Williams, as well as SIGACT chair Michael Mitzenmacher and STOC’17 PC chair Valerie King).   One component of Theory Fest would be a series of … Continue reading Theory Fest short presentations – call for suggestions

The success of TOC is due to the intrinsic intellectual merit of our field but also due to many fruitful connections: connections between subfields of TOC (see Avi Wigderson’s depth through breadth), connection with Mathematics, connections with other fields in Science and Humanities via the computational lens, and connections with industry. All of these powerful … Continue reading TOCA-Revolution Begins: Nov 4
