Additional Information

Registration + SBC membership (or membership renewal). These categories refer to a discounted value applied when registering for SBMF/ETMF 2020 and joining SBC. This modality was created to make the sum of those benefits cheaper than acquiring each of them separately, thus being the most advantageous option for whom is not yet a member of SBC or is with his/her membership expired or about to expire.

Student registration. Registration fees for students are only available to those who are currently enrolled in undergraduate or graduate courses at Higher Education Institutions and do not apply to post-doc researchers. When registering through the ECOS system, an electronic proof of the student status with affiliation, participant's name, course which he/she is enrolled at, and current date will be required. Only after SBC verifies the document (which can take up to 1 business day to be analyzed) it will be possible to proceed with the payment of registration. To avoid any inconvenience, it is recommended not registering for SBMF/ETMF 2020 in the last day of the registration range. Payment options will be available only after the SBC's validation. Registrants will receive informative e-mails in all stages of their registration for SBMF/ETMF 2020.

Registration for SBMF authors. Papers accepted to SBMF will be published in a volume of LNCS. At least one author (professional or student) of each accepted paper must be registered for SBMF 2020 and pay the author fee. Authors can not use the registration benefits (exemption or 50% discount) granted by SBC to affiliated institutions. The author fee must be paid until October 30, 2020.

Printed proceedings. All registered papers will receive a printed copy of the SBMF 2020 proceedings. Non-author participants interested in printed copies of the conference proceedings must pay the Printed Proceedings additional fee.

Payment options. Registrations can be paid by bank ticket, credit card, debit to a Bank of Brazil account, note of commitment or billing through the ECOS system. Registrations can be made until the last day of SBMF 2020, but payments by debit account and bank ticket will be closed on November 20, 2020. After that date, registration can be paid only by credit card, note of commitment, and billing.

Registrations to be paid by note of commitment or billing. Registrants must access the ECOS system and make their registration by selecting either "Note of commitment" or "Billing" as payment option. Once the payment has been requested, the system will provide the required information that must be in the note of commitment or billing request.

Cancellation policy. Registration cancellation requests made until November 13, 2020 may have a refund of 70% of the amount paid for registration in SBMF / ETMF 2020, the remaining 30% being used to cover administrative costs. After that date, there will be no refund of any paid amount. This policy applies to cancellation of both registration and author fee. To request cancellation, registrants must send an e-mail to faturamento@sbc.org.br.

Submission instructions

We invite submissions of papers with a strong emphasis on formal methods, whether practical or theoretical, in the following categories:
  • 1 - Regular papers (limit of 16 pages);
  • 2 - Journal-first papers (limit of 4 pages).
Page limits include references and any appendices. When submitting the paper, the authors should select the appropriate submission category. Contributions should not be simultaneously submitted for publication elsewhere. They should be written in English and prepared using Springer’s Lecture Notes in Computer Science (LNCS) format.
More information available in the following link:

Papers submitted to Category (1) should present unpublished and original work that has a clear contribution to the state-of-the-art on the theory and practice of formal methods. Papers will be judged by at least three reviewers on the basis of originality, relevance, technical soundness and presentation quality and should contain sound theoretical or practical results. Industry papers should emphasize practical application of formal methods or report on open challenges.

Papers submitted to Category (2) should provide a concise summary of an outstanding journal paper published by the same authors, besides considering an updated reflection about the achieved results: what has been done since the original publication, and what are the current challenges. The submission must explicitly include full bibliographic details (including a DOI) of the journal publication it is based on. The published journal paper must adhere to the following criteria:

  • It is clearly within the scope of the conference.
  • It has been made available in a journal (online or in print) not before 1 January 2018.
  • It is not an extended version of a selected conference paper.
  • It has not been presented at, and is not under consideration for, other journal-first tracks.
Our goal with Category (2) is to further enrich the SBMF program, bringing about results that have been published but not presented in any conference yet. In this way, we want to foster interesting discussions that might be relevant to attendees and authors. Papers submitted to this category will be judged based on the aforementioned recommendations and criteria.

Submissions for all categories should be made via the following link:

Ouro Preto

Ouro Preto is located about 100/km from the capital of Minas Gerais state, Belo Horizonte, in a region which is a cultural center with various well-known poets, musicians, and Brazilian visual artists. Due to its architecture, composed by the biggest group of Baroque works in Brazil, Ouro Preto was the first Brazilian town entitled as World Cultural Heritage by UNESCO in 1980.
Born from explorer Antônio Dias’s discovery of “ouro preto” (black gold) in the Tripuí riverbed in the 17 th century, the history of the city could be conflated with Brazil’s. Ouro Preto enjoyed its gilded age during the Ciclo do Ouro , when it was the stage for the Inconfidência Mineira, a separatist movement led by Tiradentes and motivated by the Portuguese crown’s high taxation of gold.
The decline of Ouro Preto’s mines, at the end of the 18 th Century, led much of the population to abandon the city. This migration, on the other hand, led to the preservation of its historical center, the largest example of Baroque architecture in the world. Especially noteworthy are the works of Aleijadinho and Master Ataíde.
Rich in history, culture, education, and entertainment, the town has an intense cultural agenda, organized in partnership with UFOP and some of the most important artistic and cultural events of the country.
Inspiration for poets and artists, for mysterious legends and stories that have persisted generation after generation among its inhabitants, Ouro Preto is an icon survived in Tomás Antônio Gonzaga’s poetry, in Guignard’s canvases and in the imagination of all who have the chance to visit.


Church Nossa Senhora do Pilar

This building was completed in 1731 as a replacement for the original main church, constructed between 1700 and 1707 of mud and wood reinforcements. It is considered the pinnacle of baroque opulence and dramatic quality. Its austere facade is a sharp contrast to the lavish interior, decorated with 434 kg (956 lb) of gold and 400 kg (880 lb) of silver. Francisco Xavier de Brito, one of Aleijadinho's mentors, is believed to have designed the main altar. Don't miss the Museu de Arte Sacra in the basement of this church.
Informations of other curches can be seen here.


Museum of the Inconfidência

The Museum of the Inconfidência is the second most visited museum in Brazil. It is dedicated to those who died in a failed rebellion movement Inconfidência Mineira (1789) for Brazilian independence from Portugal. It offers a rich portrait of the local society at the time. It is located at Tiradentes square, right in front of a monument dedicated to Joaquim Jose da Silva Xavier the most famous activist of the Inconfidência movement.


Santa Rita Gold Mine

Opened in 1704, this is oldest mine in town. This mine was dug by slaves and shows the contrast between hand dug mines and industrially dug mines. It's digging produced a maze of tunnels. Guided visits allow tourists to explore some parts of the ancient mine.


Mina do Chico Rei

The legend says this mine was property of "Chico Rei" (fictional name), a former slave who won his freedom and become rich. He was the only black who owned a gold mine in colonial times . It is located in the backyard a particular property . The mine is well conserved. In the mine walls are cavities where the deposited gold was collected during the day. The total area of 8 square kilometers with 175 open galleries , excavated in three levels deep.


Train ride from Ouro Preto to Mariana

The train ride allows to know history and beautiful scenery of the cities of Ouro Preto and also the historic town of Mariana, through the old railway built in 1883, with 18 kilometers long. The carriages and the locomotive were handmade renovated, preserving its original features - keeping the same design of the old trains , with wooden interiors. Panoramic windows allow a full view of the beautiful countryside, including waterfalls. The Ouro Preto and Mariana stations complete in 2016, respectively, 128 and 102 years.
