Authors are invited to submit papers presenting original and unpublished research on theoretical aspects of computer science.
Typical areas include (but are not limited to):

  • • algorithms and data structures, including: design of parallel, distributed, approximation, parameterized and randomized algorithms; analysis of algorithms and combinatorics of data structures; computational geometry, cryptography, algorithmic learning theory, algorithmic game theory;
  • • automata and formal languages, including: algebraic and categorical methods, coding theory;
  • • complexity and computability, including: computational and structural complexity theory, parameterized complexity, randomness in computation;
  • • logic in computer science, including: finite model theory, database theory, semantics, specification verification, rewriting and deduction;
  • • current challenges, for example: natural computing, quantum computing, mobile and net computing, computational social choice.

Paper Submission and Format

Submissions can be uploaded to EasyChair: https://easychair.org/conferences/?conf=stacs2019.
Authors are invited to submit a draft of a full paper with at most 12 pages (excluding the title page and the references section). The title page consists exclusively of the title of the paper, author information, and abstract.
The usage of pdflatex and the LIPIcs style file (see http://www.dagstuhl.de/en/publications/lipics) are mandatory; no changes to font size, page geometry, etc. are permitted. Submissions not in the correct format or submitted after the deadline will not be considered.
The paper should contain a succinct statement of the issues and of their motivation, a summary of the main results, and a brief explanation of their significance, accessible to non-specialist readers.
Proofs omitted due to space constraints must be put into a clearly marked appendix, to be read by the program committee members at their discretion.
Simultaneous submission to other conferences with published proceedings or to journals is not allowed. PC members are excluded from submitting.
There will be a rebuttal period for authors between November 26—29, 2018. Authors will receive the reviews of their submissions (via EasyChair) and have three days to submit rebuttals (via EasyChair). These rebuttals become part of the PC meeting, but entail no specific responses.


Accepted papers will be published in the proceedings of the symposium. As usual, these proceedings will appear in the Leibniz International Proceedings in Informatics (LIPIcs) series, based at Schloss Dagstuhl. This guarantees perennial, free and easy electronic access, while the authors retain the rights over their work. With their submission, authors consent to sign a license authorizing the program committee chairs to organize the electronic publication of their paper, provided the paper is accepted.

Local Guide

Arrival by train or plane

Berlins airports are Airport Schoenefeld (SXF) and Airport Tegel (TXL).

From Tegel Airport (TXL)
There are several bus lines leading into city center. The bus line X9 stops at U Ernst-Reuter-Platz. Note that no train, metro, or tram operates from and to Tegel airport directly.

From Schoenefeld Airport (SXF)
The S-Bahn (S9, S45) operates from Schoenefeld Airport (SXF) to the city center. The S9 stops at Berlin Hauptbahnhof (main station), S+U Friedrichstraße, S Tiergarten, and S+U Zoologischer Garten (the latter two are in walking distance to the conference site).
There are regional trains RE7 und RB14 (sometimes also called "Schoenefeld Express") operating between SXF and S+U Zoologischer Garten twice per hour (between 4 am to 11 pm). The trains stop additionally at S+U Alexanderplatz and Berlin Hauptbahnhof (main station), amongst others.
Be aware of the fact that SXF is located in the fare zone C: That said, in order to go to fare zone A (where TU Berlin is located) by public transport, you are requested to purchase an "ABC" ticket.

From Berlin Central Train Station (Hauptbahnhof, HBF)
There are several S-Bahn lines going to S Tiergarten or S+U Zoologischer Garten. If you plan to come by train you may consider to use the provided gadget.

Lunch options on and around TU Berlin campus

On and around TU Berlin there are several lunch options.
On the TU Berlin campus, you can find several mensas, canteens, and cafés. However, note that at some places, you are only able to pay using a so-called MensaCard (in the map, indicated by blueish icons). At all of our listed lunch options around TU campus, at least one vegetarian dish is usually offered.
Lunch options with only MensaCard-payment (blueish icons):

Lunch options with cash-payment (green icons): In addition, there are plenty of restaurants around TU Berlin, for example at (and on the way from TU Berlin to) Savignyplatz. A small selection of cuisines close to TU campus is the following: Indian Cuisine, Italian Cuisine, Chinese Cuisine, Croatian Cuisine, Traditional Cuisine, (Vegetarian) Döner


Berlin offers many options for accommodation (like hotels, hostels, etc.). Also around the TU Berlin, there are several options. Some randomly selected hotels in walking distance to the TU Berlin are: Moreover, around the Zoo and Savignyplatz there are many options, which are still in a walking distance of 20 minutes.

Thursday: A Free Evening

Berlin is a living city, throughout the day and evening. Each district of Berlin has its own character and charme. Charlottenburg, the district where TU Berlin is located in, is home for a high variety of things to do in the evening: Schaubühne* (theater), Wühlmäuse* (cabaret), Deutsche Oper* (opera), cinemas* (four from the Yorck kino group, usually displaying movies in original language; or the Zoopalast), or simply drink and eat (see right-hand side map).

Further theatres are, for instance, the Deutsches Theater* or the Berliner Esemble*. In case you like classical music: Berliner Philharmonie*.

There is, as in every larger city, a high number of restaurants and bars worth to visit. On the right-hand side map, you find a small collection of options, several close to TU Berlin, some slightly further away (you possibly need to zoom out).

* Be aware of the fact that in case, you may need to order/reserve tickets in advance.
