The Organization Committee (OC) and the Chairs of ALGO 2020 decided to run all the conferences online in a virtual way.

Welcome to ALGO 2020

ALGO is an annual meeting combining the premier algorithmic conference European Symposium on Algorithms (ESA) and a number of other specialized conferences and workshops, all related to algorithms and their applications, making ALGO the major European event for researchers, students and practitioners in algorithms.

ALGO 2020 was meant to be held in Pisa, in Tuscany, and organized by the Computer Science Department of the University of Pisa, Italy. The town hosts the University of Pisa, which has a history going back to the 12th century. Leonardo Fibonacci and Galileo Galilei are among the prominent scientists who were born in Pisa.


Among the most important monuments of the city is the famous Piazza del Duomo, also called Piazza dei Miracoli (Miracles Square), declared World Heritage Site, with the Cathedral built between 1063 and 1118 in Pisan Romanesque style and the Leaning Tower, a bell tower of the twelfth century, today one of the most famous Italian monuments in the world because of its characteristic inclination. Pisa has 20 other historic churches, several medieval palaces and various bridges across the Arno river.

We combat harassment and discrimination in our scientific community, adopting a code of conduct for ther ALGO conferences.

Keynote Speakers

Pierre Fraigniaud

IRIF, Université Paris-Diderot, France

Pierre's main research interest is parallel and distributed computing, and specifically the design and analysis of distributed algorithms and data structures for networks. He is member of the Editorial Boards of Distributed Computing (DC), and Theory of Computing Systems (TOCS). He was Management Committee Chair of the European COST Action 295 DYNAMO on Algorithmic Aspects of Dynamic Networks. He is currently Chair of the national working group Complexity and Algorithms (CoA) of GdR IM. In 2012, he received the Silver Medal from CNRS, and, in 2014, the Prize for Innovation in Distributed Computing.

Dan Gusfield

University of California, Davis, USA

Dan's primary interests involve the efficiency of algorithms, particularly for problems in combinatorial optimization and graph theory. These algorithms have been applied to study data security, stable matching, network flow, matroid optimization, string/pattern matching problems, molecular sequence analysis, and optimization problems in population-scale genomics. Currently, he is focused on string and combinatorial problems that arise in computational biology and bioinformatics. He served as chair of the computer science department at UCD from July 2000 until August 2004, and was the founding Editor-in-Chief of The IEEE/ACM Transactions of Computational Biology and Bioinformatics until January 2009.

Ronitt Rubinfeld

CSAIL, MIT, Cambridge, USA

Ronitt's main research interests are in algorithms for data sets that are so large that one cannot view the entire input--namely, sublinear time algorithms. Such algorithms have been applied in a variety of settings, including the processing of large graphs and when studying data from distributions over large discrete domains. Ronitt gave an invited lecture at the International Congress of Mathematicians in 2006. She became a fellow of the Association for Computing Machinery in 2014 for contributions to delegated computation, sublinear time algorithms and property testing. She published over 100 papers, mostly in top TCS conferences and journals.

Martin Savelsbergh

Georgia Tech, USA

Martin's research interests are in mathematical modeling, operations research, optimization methods, algorithm design, performance analysis, logistics, supply chain management, and transportation systems. He has published over 150 research papers in many of the top optimization and logistics journals, and has a track record of innovative techniques for solving large-scale optimization problems in a variety of areas. Ongoing research projects include innovations in last-mile delivery, advances in dynamic ride-sharing, methods for multi-objective optimization, and dynamic management of time-expanded networks. Martin Savelsbergh is the Editor-in-Chief of Transportation Science, the flagship journal of INFORMS in the area of transportation and logistics.

Clifford Stein

Columbia University, USA

Cliff's research interests include the design and analysis of algorithms, combinatorial optimization, operations research, network algorithms, scheduling, algorithm engineering and computational biology. He has published many influential papers and has occupied a variety of editorial positions. His work has been supported by the National Science Foundation and Sloan Foundation. He is the winner of several prestigious awards including an NSF Career Award, an Alfred Sloan Research Fellowship and the Karen Wetterhahn Award for Distinguished Creative or Scholarly Achievement. He is also the co-author of two popular textbooks: Introduction to Algorithms, and Discrete Math for Computer Scientists.

  • Administrative support: Letizia Petrellese, Camilla Sovani, Università di Pisa


Please note that due to covid-19, the financial scheme is different from that of previous editions as attendants do not pay any fee: the costs are split among accepted papers, not among attendants, and the registration fee is by paper, not by author. Each accepted paper should pay a registration fee at the conference rate unless it is a student paper. (Definition: a student paper is a paper where all authors are students, and the registration is free.) If the same author wants to register for multiple papers, a fee should be paid for each paper. In any case, registration is generally considered a pre-requisite for proceedings publication (except for WAOA). As required by the Steering Committee, the author registering for a paper accepted at ESA 2020 should be an EATCS member (necessary condition, please provide your active EATCS member ID). Registration deadlines and charges are as follows.

Registration Deadline Fee
Student paper August 17, 2020 FREE (zero €)
Non-student paper in ATMOS/ESA/WABI August 17, 2020 100 €
Non-student paper in ALGOCLOUD/ALGOSENSORS/WAOA August 17, 2020 40 €
Attendant (registration via email) September 5, 2020 FREE (zero €)

For student papers, please send us an email to algo2020pisa@gmail.com with subject line "registration - student paper" in which each author individually declares to be currently a student and not holding a PhD. Then proceed to register as indicated below.

Registration, invoicing, and related logistics activities, are managed by our organizing secretariat.
