Theory Fest short presentations – call for suggestions

October 22, 2016

As mentioned before on this blog,   STOC 2017 will be part of an expanded “Theory Fest” ( 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 presentations to highlight some of the best theoretical work in the past two years from other conferences or journals. (A non-exhaustive list of sample venues is ICALP,SODA, CRYPTO, LICS, PODS, PODC, QIP, SPAA, KDD, CCC, SIGMETRICS, Transaction on IT, WWW, ICML/NIPS , Science/Nature, etc..) Invited papers from these venues  will be presented in short (20-30 minute) plenary presentations at Theory Fest.

We (the sub-committee in charge of this component) seek suggestions of theoretical papers that have made breakthrough advances, opened up new questions or areas, made unexpected connections, or had significant impact on practice or other sciences. Anyone is welcome to contact us, but we especially invite members of PCs or editorial boards in various venues to send us suggestions.

If you can think of any recent result that satisfies these criteria, or have any related questions, please email . Suggestions for presentations should include the following information:

  1. Name of the paper and authors.
  2. Publication venue (conference / journal), with publication date no earlier than January 1 2015.
  3. Short (1-3 paragraph) explanation of the paper and its importance.
  4. (Optional) Names of 1-3 knowledgeable experts on the area of this paper.

To ensure maximum consideration, please send us all these suggestions by December 12,  2016. Self-nominations are discouraged.

Thank you,

TOCA-Revolution Begins: Nov 4

October 14, 2016

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 connections contribute to the impact and vitality of TOC.

In this spirit, the theory group at Stanford and our theory colleagues all around the Silicon Valley are establishing a forum for continuous collaboration (through meetings and electronic means) between theoreticians in industry and academia in the SF Bay Area. We name it TOCA-SV. TOCA stands for Theory of Computing Associated and also, quite appropriately, means touches in Spanish. Like others, calling for a revolution: I hope that TOCA groups will surface all over.

Our first meeting will take place at Stanford on November 4th. Please join us if you are around and please don’t forget to register.

Students who want to present in this event (in a lightning-talk session) are asked to email us at Please specify your name, affiliation, adviser (if you have one), year and email address. We will try to accommodate as many as possible (but future opportunities are planed).

Finally, to stay in touch for future information, please join our Google group.

Occupy TOC, power to the people, onwards and upwards or whatever seems appropriate here🙂

Live from Princeton, NJ: Avi60

October 4, 2016

I hope to see many readers of this blog in person tomorrow for the workshop in honor of Avi Wigderson 60th birthday (Wed-Sat), which will feature a collection of great speakers talking on a variety of areas in theoretical computer science and mathematics.

But, if you can’t make it in person, the talks will be streamed live on the workshop’s website. These talks can be a great resource for anyone, but I especially encourage beginning graduate students to watch them. Watching the kind of high level talks that are in this workshop (as well as other places, including the theoretically speaking and open lectures series of the Simons Institute of Computing) can be extremely useful for students trying to figure  out what area of research to focus on.


An optimal weather variant of the sum of squares algorithm

September 18, 2016

As I mentioned before, this term Pablo Parrilo, David Steurer, Pravesh Kothari, and I are teaching two sister seminars at Harvard/MIT and Princeton on the Sum of Squares algorithm. See the website  for details, lecture notes, as well as links to lecture videos and how to sign up to follow the course on Piazza.

But, if you want the short, in-person, better weather version, you might want to sign up for the winter Course David Steurer and I will teach on this topic January 4-7 2017 in UC San Diego.

We hope to touch on how the sos algorithm interacts with questions in computational complexity, approximation algorithms,  machine learning,  quantum information theory, extremal combinatorics, and more.

Proofs, beliefs and algorithms through the lens of Sum of Squares

August 27, 2016

This fall I will be teaching a graduate seminar on the Sum of Squares algorithm. Actually, it will be two “sister seminars”. In the Cambridge/Boston area, I (with possibly some guest lectures by Pablo Parrilo) will be teaching the course on Fridays 10am-1pm, alternating between Harvard and MIT. In Princeton, David Steurer and Pravesh Kothari will teach the course on Mondays.

If you are interested in attending the course, or even following it remotely, please see the course web page, and also sign up for its Piazza page (people without a Harvard email can use this form). David and I will be trying to write fairly complete lecture notes, which we will post on the website, and I might also post some summaries on this blog.

Here is the introduction for this course:

Call for proposals for FOCS’16 workshop/tutorial (half-)day

August 4, 2016

Following the proud tradition of previous STOC/FOCS conferences, FOCS’16 will also have a (half) day of workshop/tutorials on Saturday, October 8th, right before the conference starts.

You are invited to submit your proposal of workshop or tutorial by August 31st; see details here.

In short: you just need to propose an exciting theme and arrange the speakers. We will take care of the logistic details like rooms, AV, coffee break, etc.

Note that this is only a half-day event (2:30pm-6pm) since in the morning there will be another not-to-be-missed event: A Celebration of Mathematics and Computer Science: Celebrating Avi Wigderson’s 60th birthday (which actually starts already on Thursday, October 5th). See Boaz’s announcement here.

If you have any questions about the FOCS workshops, feel free to get in touch with the coordinators: Aleksander Madry and Alexandr Andoni.

TheoryFest 2017 – guest post by Sanjeev Arora

STOC Theory Fest 2017 (Montreal June 19-23)

Sanjeev Arora, Paul Beame, Avrim Blum, Ryan Williams


SIGACT Chair Michael Mitzenmacher announced at the STOC’16 business meeting that starting in 2017, STOC will turn into a 5-day event, a Theory Fest. This idea was discussed at some length in a special session at FOCS 2014 and the business meeting at STOC 2015. Now the event is being planned by a small group (Sanjeev Arora, SIGACT ex-chair Paul Beame, Avrim Blum, and Ryan Williams; we also get guidance from Michael Mitzenmacher and STOC’17 PC chair Valerie King). We’re  setting up committees to oversee various aspects of the event.


Here are the major changes (caveat: subject to tweaking in coming years):


(i)  STOC talks go into 3 parallel sessions instead of two.  Slight increase in number of accepts to 100-110.

(ii)   STOC papers also required to be presented in evening poster sessions (beer/snacks served).

(iii) About 9 hours of plenary sessions, which will include: (a) Three keynote 50-minute talks (usually prominent researchers from theory and nearby fields) (b)  Plenary 20-minute talks selected from the STOC program by the STOC PC —best papers, and a few others. (c) Plenary 20-minute talks on notable papers from the broader theory world in the past year (including but not limited to FOCS, ICALP, SODA, CRYPTO, QIP, COMPLEXITY, SoCG, COLT, PODC, SPAA, KDD, SIGMOD/PODS, SIGMETRICS, WWW, ICML/NIPS), selected by a committee from a pool of nominations. (Many nominees may be invited instead to the poster session.)

(iv) 2-hour tutorials (three in parallel).

(v)    Some community-building activities, including grad student activities, networking, career advice, funding, recruiting,  etc.

(vi)   A day of workshops; 3 running in parallel. (Total of 18 workshop-hours.)


Our hope is that workshop day(s) will over time develop into a separate eco-system of regular meetings and co-located conferences (short or long). In many other CS fields the workshop days generate as much energy as the main conference, and showcase innovative, edgy work.


Poster sessions have been largely missing at STOC, but they have advantages: (a) Attendees can quickly get a good idea of all the work presented at the conference (b) Grads and young researchers get more opportunities to present their work and to interact/network, fueled by beer and snacks. (c)Attendees get an easy way to make up for having missed a talk during the day, or to ask followup questions. (d) Posters on work from other theory conferences broadens the intellectual scope of STOC,


We invite other theory conferences to consider co-locating with the Theory Fest. To allow such coordination, in future the location/dates for the Theory Fest will be announced at least 18 months in advance, preferably 2 years. Even for 2017 it is not too late yet.


Finally, we see the Theory Fest as a work in progress. Feedback from attendees will be actively sought and used to refashion the event.
