January 8, 2021
We decided to make the closing remarks right after the end of the technical sessions.
So, please join us in the auditorium (and from there go to Zoom) at 16h20.
After that, everybody is invited to go back to the lobby.
January 7, 2021
The proceedings are freely available for the next month.
January 5, 2021
Due to some technical issues, we made two changes in the program:
1) the talk for paper "Improved Upper Bounds on the Growth Constants of Polyominoes and Polycubes", which will be given by Mira Shalah, went from Tuesday to 11h on Thursday, in Session 8.
2) the talk for paper "Dynamically Optimal Self-Adjusting Single-Source Tree Networks", by Chen Avin, will be replayed at 16h on Friday, in Session 13.
January 5, 2021
There has been a small program change: the talk for paper "Ordered Strip Packing", which will be given by Willem Sonke, went from 11h on Thursday to 15h40 on Friday, in Session 13.
January 3, 2021
The program with all of the programmed
activities is finalized.
Titles and abstracts for the plenary talks as well as the posters are available.

We apologize for taking very long to give you news about LATIN 2020.
The Local Organizing and the Steering committees have decided to run LATIN online from 5 to 8 January 2021.
We do hope that holding the event online will make it possible for everyone to take part and that this will make the meeting an exciting one.
The proceedings are in production and the proofs should be received by the authors anytime soon.
April 20, 2020
The Local Organizing Committee and the Steering Committee have decided to postpone the conference to 2021.
Final dates and further information will be given in the future.
We hope you are all safe and well and we hope to see you at the conference in 2021!
March 13, 2020
After careful consideration of the current Coronavirus outbreak, the LATIN 2020 Local Organizing Committee decided to put the registration temporarily on hold.
We kindly ask all participants to not make any travel or
accommodation arrangements at this moment.
The Local Organizing Committee will continue monitoring the latest developments carefully.
We will update this site with further news as soon as we can.
The main concern of the Local Organizing Committee is the health of
all conference participants and the limitation of the spreading of this
The situation changes every day and some countries and some institutions are imposing different restrictions.
We would like to wish you all the best and thank you for your support of LATIN 2020!
LATIN (Latin American Theoretical Informatics) was born in 1992, when a group of Latin American researchers, under the leadership of Imre Simon (São Paulo, Brazil), launched the first of a series of symposia in theoretical computer science, to be held triennially in Latin America. Since 1998 it has been held biennially: Valparaiso, Chile (1995); Campinas, Brazil (1998); Punta del Este, Uruguay (2000); Cancún, Mexico (2002); Buenos Aires, Argentina (2004); Valdivia, Chile (2006); Búzios, Brazil (2008); Oaxaca, Mexico (2010); Arequipa, Peru (2012); Montevideo, Uruguay (2014); Ensenada, Mexico (2016); and Buenos Aires, Argentina (2018).
We are excited to have this meeting, so close to our hearts, back in São Paulo in 2020.
For further information on LATIN, please visit the LATIN Symposium Website.

Registration closed in December 28.
In case of any changes to the submitted registration or any problem, please contact the organisers.
Fees and payment deadlines
The payments are in the official currency of Brazil, the Brazilian Real (BRL).
|Deadline||Regular||Speakers and Steering Committee members|
|December 27, 2020||100 BRL (approx. 18 USD)||0 BRL (free)|
Payments will be accepted via credit card. For Brazilians, you may also pay via "débito" or "boleto" up to December 30, 2020.
All cancellation and changes must be received by December 30, 2020.
The submission process must be completed electronically through EasyChair. A paper abstract must be submitted by 17 November 2019.
Submitted papers are limited to twelve (12) single-column letter/A4-size pages in Springer LNCS format, and must be written in English. This page limit includes figures and references. An optional appendix (to be read at the program committee's discretion) may be included if desired. Submissions deviating substantially from this format risk rejection without consideration of their merits.
Authors should consult Springer's authors' guidelines and use their proceedings templates, either for LaTeX or for Word, for the preparation of their papers. Springer's proceedings LaTeX templates are also available in Overleaf. Springer encourages authors to include their ORCIDs in their papers. For each accepted paper, the corresponding author, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made. Authors who have included their email addresses in their papers will receive an email roughly four weeks after publication of the proceedings, linking them to their personal My Springer page. From here, they will be able to download the pdf of the entire volume. In addition, authors and editors are entitled to a 40% discount off Springer publications. Details are given on MySpringer page.
Manuscripts submitted to LATIN should present original, previously unpublished work. At the time of their submission to LATIN, manuscripts must not have been submitted to any other conference or scientific journal. Simultaneous submission of papers to any other conference with published proceedings is not allowed.
For each accepted paper at least one author must register and attend the symposium to present it. Moreover, an author cannot register for multiple papers. That is, each accepted paper must have its own registered presenter.
Imre Simon Test-of-Time Award
As of 2012, the Imre Simon Test-of-Time Award is given to the LATIN paper deemed most influential among all those published at least ten years prior to the current edition of the conference. Papers published in the LATIN proceedings up to and including 2010 were eligible for the 2020 award.
The awardee of the 2020 edition is Anne Brüggemann-Klein, for the paper Regular expressions into finite automata, published in the first LATIN, in 1992. Heartfelt congratulations!
Best Paper Award
Papers presented at the conference were considered for the LATIN 2020 Alejandro López-Ortiz Best Paper Award.
The awardees of the 2020 edition are Bruno Pasqualotto Cavalar, Mrinal Kumar, and Benjamin Rossman, for the paper Monotone Circuit Lower Bounds from Sunflowers. Heartfelt congratulations!
