CSR is an annual international conference held in Russia that is designed to cover a broad range of topics in Theoretical Computer Science. It is the sixteens conference in a series of regular events started with CSR 2006 in St. Petersburg. The list of previous CSR conferences can be found at https://logic.pdmi.ras.ru/~csr/. Conference proceedings are published in Springer's Lecture Notes in Computer Science series. A selection of extended versions of accepted papers will be published in a Special Issue of the Springer journal "Theory of Computing Systems".


Deadline for submissions: December 24, 2020 (anywhere on earth).

Notification of acceptance: February 18 February 8, 2021.

Conference dates: June 28-July 2, 2021.

Due to the situation with the COVID-19 pandemic and ongoing international travel restrictions, the event will be held in a hybrid mode. Those participants who are able to arrive in Sochi will present their papers physically, the others will give their presentations online. The talks will be scheduled between 14:00 and 19:30 (Moscow time, UTC+3) that is convenient for the majority of time zones.
