Phil Klein passed on that there's a delay at SIAM in getting the SODA 2017 CFP up, and of course we want to get out the relevant information out to the community. So he asked me to post the following:
SODA 2017: The official SIAM symposium webpage is http://siam.org/meetings/da17/. This page does not yet have the call for papers. (My understanding is that the call for papers has yet to be approved by some SIAM staff who are out this week.) The deadlines are as follows: July 6 (short abstract and paper registration), July 13 (full submission).
The symposium will take place on January 16-19, 2017, in Barcelona, Spain.
For now, you can visit http://cs.brown.edu/~pnk/#soda17 for the basic information (deadlines, submission site, and program committee).
