Authors are invited to submit an extended abstract or a full paper of at most 12 pages in English, not including references, in the LNCS format (LaTeX, as pdf; final version with source); instructions are here:

Proofs and other material omitted due to space constraints are to be put into a clearly marked appendix to be read at discretion of the referees. Papers must present original (and not previously published) research. Simultaneous submission to journals or to other conferences with published proceedings is not allowed. The proceedings of the symposium will be published in Springer's LNCS series.

We are carefully watching the situation with the Covid-19 pandemic. We hope to conduct a physical event, but it will be possible to participate in the event online for those who are unable to come due to travel restrictions or other circumstances. In case the situation in Russia does not allow us to organize a meeting in place, we are planning to move the event online but not to postpone it.
