Estonian Computer Science Theory Days /
Arvutiteaduse teooriapäevad

The Estonian Computer Science Theory Days started in 2002 as a Tallinn-Tartu event and have been organized biannually since then, from 2017 less frequently. Since 2010, they have repeatedly happened as Joint Estonian-Latvian Theory Days, including also colleagues from Riga.

The Theory Days are meant as an opportunity for Estonian--and Latvian--computer scientists of theoretical orientation to meet, learn about each other's work and socialize. The main target audience of the Theory Days is graduate students in the roles of both listeners and presenters, but the event is open to undergraduates, postdocs, faculty, anyone interested really.

The meetings take place at country hotels (nearly always a new place!) on weekends and tend to attract around 40 participants. (The meetings 2017-19, 2022 took place in cities.) The scientific programme consists of invited tutorial-like talks, regular technical talks and (on occasion) interactive seminars. You can hike, ski, play games, enjoy sauna. If you never attended, make sure you can make it to the next Theory Days!

If you wish to give a talk at the next Theory Days, please contact the organizers.

The Theory Days are organized by a standing organizing committee comprising:


The first Theory Days at Roosta in 2002 were supported by a center of excellence in research project of TUT. Those of 2003-2007 took place under the auspices of the Centre for Dependable Computing, CDC, a centre of excellence project of the Estonian state 2002-2007. In 2008, the Theory Days were supported by HITSA's Tiigriülikool programme.

From 2009 to winter 2015, the Theory Days were a meeting of the Estonian Centre of Excellence in Computer Science, EXCS, an Estonian CoE project 2008-2015 financed by the European Regional Development Fund.

At the moment, we do not have a sponsor.
