How is SODA 2027 ranked?
SODA 2027 is rated ICORE A*, CCF A. ICORE/CORE (the CORE Conference Ranking, 2026 edition) grades venues from A* (flagship) through A, B and C; CCF is the China Computer Federation's parallel A/B/C rating. That places SODA among the more selective venues within Theory, which is one reason its deadlines fill calendars early. The conference takes place in Philadelphia, Pennsylvania, USA on January 24-27, 2027. Rankings are only one input when choosing where to submit — also weigh fit, audience and timing.
