Event Start


The Brazilian Symposium on Formal Methods (SBMF) is a scientific event that has been held annually since 1998. The 26th edition of SBMF will take place in 2023 in Manaus, the capital of Amazonas. SBMF courses and lectures are dedicated to disseminating recent advances in the field of formal methods. The technical sessions of SBMF foresee the presentation of unpublished works that make clear and significant contributions to the state of the art in the theory and practice of formal methods.

The main topics discussed at SBMF include:
Formal aspects of specification languages and theoretical foundations, such as the development of new domain-specific languages, the formalization of existing languages, and the study of the foundations of software engineering. Formal aspects of systems development, such as the application of formal methods to the development of cyber-physical systems, embedded systems, and software-intensive systems. Verification and validation, such as the formal verification of the correctness of software systems, the model checking of the requirements of software systems, and the fuzz testing of software systems. Formal verification of neural networks, such as the application of formal methods to the verification of the correctness of deep learning models. Self-formalization and formal aspects in practice, such as the automation of formal methods, the use of formal methods in industrial settings, and the teaching of formal methods.

Manaus, located on the banks of the Negro River in northwestern Brazil, is in the heart of the world's largest rainforest and is one of the biggest tourist destinations in Brazil. It is also the main financial, corporate, industrial, research, technology, entertainment, and commercial center of the Northern Region of Brazil. The city is situated at the confluence of the Negro and Solimões rivers, with the Teatro Amazonas listed as a National Historic Heritage by IPHAN its greatest cultural symbol.
Manaus was home to the first higher education institution in Brazil, founded on January 17, 1909. This originated from the defunct Free University of Manáos, which dismembered the Faculty of Law, forming the embryo of the current UFAM.
The Institute of Computing of the UFAM, which has only 30 years of history, is one of the two most important centers of higher education and research and entrepreneurship in computing startups in the North and Northeast of Brazil, being recognised as a postgraduate program of international level according to the most recent ranking by Capes, an agency of the Ministry of Education that promotes research and graduate studies.

Teatro Amazonas

The main cultural and architectural symbol of the state, Teatro Amazonas, located in Largo de São Sebastião in the heart of Manaus, keeps alive much of the history of the rubber boom, the golden age of the Amazonian capital. Inaugurated on December 31, 1896, the theater surprises and delights with its grandeur.

The concert hall seats 701 people, spread between the audience and three floors of boxes. It's impossible not to be mesmerized by the concave ceiling, which features four canvases painted in Paris by the renowned Casa Carpezot. The canvases depict music, dance, tragedy, and opera. In the center hangs a majestic French bronze chandelier. The masks on the columns of the audience, which pay tribute to composers and playwrights, are also noteworthy.

The Teatro Amazonas' boca cloth is another rarity. It was created in 1894 by Brazilian artist Crispim do Amaral and depicts the confluence of the Negro and Solimões rivers.

Nowadays, the theater hosts major events organized by the State Secretariat for Culture and Creative Economy, such as the Amazonas Opera Festival and the Dance and Theater festivals; high-brow performances like those presented by the State's Artistic and Cultural Bodies; and popular shows that benefit local artists of all genres.. More information (in portugues only) can be seen here.

Provincial Palace (Palacete Provincial)

The Provincial Palace houses three museums of different kinds: the Museum of Image and Sound (MISAM), the Museum of Numismatics of Amazonas, the Tiradentes Museum, the Pinacoteca do Estado, and the Archaeology Exhibition.

The building was founded in 1874 and served as the headquarters of the Military Police of Amazonas for more than 100 years. On March 24, 2005, it was transformed into a restaurant. However, it was reopened in 2009 as a museum, and the space is now open to the public free of charge. Visitors can come to learn about the collections and art of the museums, and the space also hosts cultural events that attract children, young people, and adults. Heliodoro Balbi Square (formerly Police Square), in front of the building, is an extension of the tour to the site.

The Pinacoteca has paintings, photos, and engravings by local, national, and international artists. The Museum of Numismatics has a collection of over 35,000 pieces and ancient coins. MISAM has DVDs and CDs that can be viewed for free on site. The Tiradentes Museum honors firefighters and state police, and exhibits weapons and uniforms. The Archaeology Exhibition reproduces excavations and artifacts discovered in the region.

Event Location

The IComp, the venue of the 26th SBMF, is situated on the UFAM Campus which spans an area of about 600 hectares consisting of native and secondary forests, plateaus and floodplains, meadows, and deforested areas with plantations. Located on the east side of Manaus, the campus is enclosed by neighbourhoods and avenues.
