Welcome to the website of the 18th International Symposium on Experimental Algorithms (SEA 2020) that will be held in Catania (Italy) from the 16th to the 18th of June 2020.
SEA (International Symposium on Experimental Algorithms), previously known as Workshop on Experimental Algorithms (WEA), is an international forum for researchers in the area of the design, analysis, and experimental evaluation and engineering of algorithms, as well as in various aspects of computational optimization and its applications.
The Conference will be held at the Benedictine Monastery of “San Nicolò”, a unique place that tells us about the human and historic events of the city on the slope at the foot of Etna, from the ancient times until today.
The proceedings of SEA 2020 will be published in the Leibniz International Proceedings in Informatics (LIPIcs) open-access series. A special issue of selected papers will be published in the ACM Journal of Experimental Algorithmics.
March 2020: the situation surrounding COVID19 outbreak has evolved rapidly and is endangering the health and safety of everyone, which are for us among the highest priorities. Thus, based on the health situation in Italy and around the world, SEA 2020 conference leadership has decided that the most prudent measure is to deliver the conference online to all registered attendees, rather than by a physical meeting.
Thus, we will implement the meeting by an online platform that will provide our attendees around the world a new conference experience.
We plan to support audio and video presentations that should be linked to papers.
Specifically SEA 2020 will be held online using the Microsoft Teams platform.
SEA 2020 organizers will be updating the web page and send via email plans for remote participation, as we develop them.

"I am reborn from (my) ashes even more beautiful", the inscription on Porta Ferdinandea, after 1860 entitled Porta Garibaldi, a triumphal arch built in 1768 to commemorate the marriage of King Ferdinand III of Sicily and Maria Carolina of Habsburg-Lorraine. It is located between Piazza Palestro and Piazza Crocifisso, at the end of Via Giuseppe Garibaldi.
Catania is the second largest city in Sicily. It is located on the eastern coast of Sicily at the foot of Mount Etna, the biggest volcano in Europe. Its metropolitan area reaches one million inhabitants, being the major transport hub and economic centre in Sicily. It is also a university city where you will enjoy a busy downtown and an active nightlife.
The history of Catania is dating back 2700 years. The city has been dominated by several different cultures, among which Greeks, Romans, Arabs, Normans and Spanish. Thanks to its port, the city has been always a rich commercial centre. Since Catania is situated under the biggest active volcano in Europe, it has been destroyed many times in the past. Moreover, like most of eastern Sicily, after the great earthquake of 1693 Catania has been rebuilt. As a consequence, Catania is a city where you can find a great variety of landscape and architecture. In particular it is well known for its particular baroque architecture and urban design. The downtown area is a World Heritage Site.
One of the best features of Catania is its city centre, rich of Baroque architecture, where you can see beautiful palaces, churches and fountains. The Elephant Statue of the 17th century, in Piazza Duomo, is the symbol of the city. Every morning, except on Sundays, you can walk across two of the most fascinating markets of the city, a large fish market in a beautiful setting off Piazza del Duomo and a bustling food and clothes market off Via Etnea.
During the visit you can make a stop at "the kiosks", which act as social areas for the locals by selling refreshments, such as coffee, Lemoncello or popular unique drinks such as "seltz al limone" or "mandarino al limone". Don't miss to ascend Mount Etna or to relax on the sandy beaches of "La Plaja". You can also visit the "Riviera dei Ciclopi", a rocky volcano coast in the north of the city.
SEA aims to attract papers from both the Computer Science and the Operations Research/Mathematical Programming communities. The main theme of the symposium is the role of experimentation and of algorithm engineering techniques in the design and evaluation of algorithms and data structures. Submissions should present significant contributions supported by experimental evaluation, methodological issues in the design and interpretation of experiments, the use of (meta-) heuristics, or application-driven case studies that deepen the understanding of the complexity of a problem.
Contributions solicited cover a variety of topics including but not limited to:
The authors should submit a paper not exceeding 12 pages, including figures, title, authors, affiliations, e-mail addresses, and a short abstract. References will not be counted in the page limit. At least 10-point font should be used. Authors are strongly advised to use the LaTeX style file supplied for the LIPIcs style here. Final proceedings papers must be camera-ready in this format. A clearly marked Appendix, which will not count toward the 12 page submission limit, can be included and will be read at the referees’ discretion. All submissions have to be made via the EasyChair submission page for the conference.
Authors are encouraged to include a link to the source code and/or datasets to increase confidence in the reproducibility of their experiments; the code may be read and/or executed at the referees' discretion.
Papers submitted for review should represent original, previously unpublished work or surveys of important results. At the time the paper is submitted to SEA, and for the entire review period, the paper (or essentially the same paper) should not be under review by any other conference with published proceedings or by a scientific journal. At least one author of each accepted paper will be expected to attend the conference and present the paper.
At the time of submission authors are required to specify the track to which they want submit their paper. The indication of the track should be entered as the first line of the abstract. The conference tracks are listed below.
The abstract must be submitted by January 24, 2020, AoE (extended deadline)
The full paper must be submitted by January 31, 2020, AoE (extended deadline)
The conference proceedings will be published in the Leibniz International Proceedings in Informatics (LIPIcs), a series of high-quality conference proceedings across all fields in informatics established in cooperation with Schloss Dagstuhl Leibniz Center for Informatics. SEA Proceedings volumes are published according to the principle of OpenAccess, i.e., they are available online and free of charge.
Since SEA 2008 a special issue of selected papers accepted at the conference is published in the ACM Journal of Experimental Algorithmics.

A Unesco World Heritage Site, Catania's central square, named Piazza Duomo, is a set piece of contrasting lava and limestone, surrounded by buildings in the unique local baroque style and crowned by the grand Cattedrale di Sant'Agata. At its centre stands Fontana dell'Elefante (1736), a naive, smiling black-lava elephant dating from Roman times and surmounted by an improbable Egyptian obelisk. Another fountain at the piazza's southwest corner, Fontana dell'Amenano, marks the entrance to Catania's fish market.
Legend has it that the elephant belonged to the 8th-century magician Eliodorus, who reputedly made his living by turning people into animals. The obelisk itself is said to possess magical powers that help ease Mt Etna's volatile temperament. Much younger is the 19th-century Amenano fountain. Created by Neapolitan sculptor Tito Angelini, the splash-happy piece commemorates the Amenano river, which once ran above ground and on whose banks the Greeks first founded the city of Catania, which they named Katáne.
If you walk westward from Piazza Duomo, you will enter the area of the ancient Catania (Katane). The road rising up to the hill is already an indication that you are on the way to the former Acropolis. The Greek theatre was once located on the southern slope of the former Acropolis. It was rebuilt by the Romans into a Roman theatre system with a connected Odeon. Since the Roman theatre was later partially obscured by baroque buildings, it is difficult to discern from the outside. The entrance is at Via Emanuele 266.
The auditorium of the Roman theatre with its two walkways has a diameter of 100 metres and was probably designed for approximately 7,000 spectators. The rows of seats, steps and the orchestra are made of black lava rock. The small Odeon is directly connected west of the Teatro Romano. The little theatre was also built of lava rock and is slightly higher than the big theatre.
Catania's forbidding 13th-century castle once guarded the city from atop a seafront cliff. However, the 1669 eruption of Mt Etna changed the landscape and the whole area to the south was reclaimed by the lava, leaving the castle completely landlocked. The castle now houses the Museo Civico, home to the valuable archaeological collection of the Biscaris, Catania's most important aristocratic family. Exhibits include colossal classical sculpture, Greek vases and some fine mosaics.

The Conference will be hold at the Benedictine Monastery of “San Nicolò”, a unique place that tells about the human and historic events of the city on the slope at the foot of Etna, from the ancient times until today.
The monastery was founded in 1558, it's complex is located in the historical centre of the city of Catania, with the church of San Nicolò l'Arena. It shows architectonical integration of many styles through different centuries. Although the monastery was founded in the 16th century, it was modified by two natural disasters in the 17th century.
In 1977 the monastery was donated to the University of Catania, which restored the entire structure and nowdays it hosts the Department of Humanities of the University of Catania and is 10 minutes walk from the Cathedral square. It is a late baroque monument and one of the biggest Benedictine monastery in Europe. The construction of the building started in 1500 and has continued until today.
It is an example of architectonical integration of different styles through different epochs: you can find a roman house, the cloisters and a roof garden. The monastery is a UNESCO World Heritage Site.
The International Symposium on Experimental Algorithms (SEA) was previously known, until 2008, as Workshop on Experimental Algorithms (WEA).
It is an international forum for researchers in the area of the design, analysis, and experimental evaluation and engineering of algorithms, started in 2001 at Riga, Latvia.
