This post represents my personal opinion (and only my opinion) with respect to turning STOC 2017 into a “Theory Festival.”
FOCS and STOC is where the entire theory community is supposed to come together for the benefit of the fruitful exchange of ideas between sub-areas of theory (which as Boaz mentioned, has been one of the sources of the community’s success). But this beautiful vision is threatened by two growing trends to worry about:
- More and more researchers in specific sub-communities abandon FOCS and STOC for the benefit of specialized venues that provide more effective exposure to their work.
- Even the FOCS-STOC experience gets fragmented as people tend to attend talks in areas closer to their own research (it is hard to know what to attend out of so many talks outside of one’s area).
The second issue could be addressed with a strong plenary program that would focus the attention of the entire community. This does not seem to be controversial and so I believe that STOC 2017 will have such a program, which is great. The second issue is much more problematic. We can no longer expect all of the strongest work in theory to be submitted to FOCS/STOC and I would think that having strong specialized venues should be encouraged. It is therefore difficult to expect researchers from area X that was “lost to FOCS/STOC” to attend the event just for the FOCS/STOC papers. In my mind, the only way to get them back is to offer a strong program in area X in addition to the plenary program that would allow them to stay connected with other areas of theory. This will require some effort and does not come for free as it will reduce the centrality of FOCS/STOC talks within the more general event. So this is the place to ask: are we really serious about a pan-theory event or are we content with keeping FOCS/STOC a place where a fraction of the theory community meets? Are we serious enough to give up a little bit of our entitled attention?
Currently, a large group of good intentioned individuals, led by the SIGACT executive committee, is considering designs for STOC 2017. This group is trying to be as attentive as possible to the voices coming out of the entire community. The problem is that in such a committee work it is very tempting to go for a conservative small change that will not upset anyone (but may gain too little). As the set of reasonable constraints and goals is impossible to completely satisfy, it is tempting to concentrate on not losing anything STOC already is rather than on gaining something new for the sake of what STOC can become. Being a romantic, I wish there was a hope to be just a little bit bolder!
To be less vague, let me conclude with the design of a pan-theory event that I would have chosen. This would be an event that would be more attractive for me to attend and much more attractive for researcher from the areas of theory that are underserved by STOC:
A STOC PC will select its program as usual (but with full flexibility regarding the number of accepted papers). An organizing committee will design the program of the theory festival. This committee will have representatives from the STOC PC but also from many other subareas of theory. The program will have three parts:
- A plenary session designed by the organizing committee and aimed to present only what the entire community should hear about.
- An afternoon session in many parallel tracks containing a collection of 3-5 days workshops (featuring STOC papers as well as other papers). These workshops will be curated by the organizing committee. For natural areas (various Algorithms areas, Complexity, ML, Econ, Cryptography, Quantum Computing, etc) representatives of the organizing committee will be setting up a workshop program (as they would do for an Oberwolfach/Simons/Banf … workshop). The committee can also accept other workshop proposals.
- An evening session that will include poster sessions (having guaranteed spots for all STOC papers).
The main challenge I see is to allocate a venue with many rooms for the parallel sessions. STOC papers will get a little bit less “formal attention” but will probably get on average more “substantial attention.” In particular, papers that deserve the attention of the entire community will be presented in the plenary session, while other papers will get the attention of their respective subcommunity (as they currently do). In addition, the poster session will give a more relaxed and interactive forum for cross-area interactions.
