Welcome 3 Welcome Dear GECCO attendees, Welcome to the Genetic and Evolutionary Computation Conference (GECCO). After the tremendously successful GECCO 2019 in Prague, Czech Republic, GECCO came back to the Americas: to Cancún, México. Unfortunately, and because of the coronavirus crisis, GECCO became, for the first time, an online conference. GECCO is the largest peer-reviewed conference in the field of Evolutionary Computation, and the main conference of the Special Interest Group on Genetic and Evolutionary Computation (SIGEVO) of the Association for Computing Machinery (ACM). GECCO implements a rigorous and selective review process to identify the most important and technically sound papers to publish. The technical program is divided into thirteen tracks reflecting all aspects of our field and each of these tracks were chaired by two experts who managed the review process and made the decisions on the papers in coordination with the Editor-in-Chief. This year, we received 415 papers and accepted 149 of them, which results in a 36% acceptance rate. Those papers will be presented during the online conference using live streaming. We additionally accepted 132 posters that will also be presented in two online posters sessions. Besides the technical tracks, GECCO includes 42 tutorials selected from among 54 proposals as well as 21 workshops reflecting important topics in our field. They will take place during the first two days of the online conference, together with several competitions. We are thrilled to welcome as keynote speakers to Leslie Valiant, from Harvard University and Kalyanmoy Deb, from Michigan State University. We are also honored that Darrell Whitley will give the SIGEVO keynote this year. We would like to thank all authors for submitting their work to GECCO 2020. We also wish to thank all the tutorial speakers as well as to the workshop and competition organizers. The organization of a conference like GECCO is a tremendous task relying on many people. We sincerely appreciate their work. We would like to thank first to all our chairs: track, tutorials, workshops, publicity, competitions, late breaking abstracts, and hot off the press. We also thank the organizers of the Humies, and of Women@GECCO as well as to the members of our program committee. Some members of the organization team deserve a special mention and recognition: José A. Lozano, Editor-in-Chief, Josu Ceberio, Proceedings Chair, Arturo Hernández Aguirre, Local Chair and Gregorio Toscano Pulido, who was Publicity Chair but played a key role by developing a system that could make possible an online conference with a more friendly user interface. All of them spent long hours working to make this conference possible. We also thank Ahmed Kheiri for allowing us to use his algorithm to optimize the schedule of the conference. It is also worth mentioning the hard work done by Brenda Ramirez and Roxane Rose who helped us with the registrations and the logistics of the event. Finally, we also thank Franz Rothlauf, Enrique Alba, Darrell Whitley, Jürgen Branke and Peter Bosman from SIGEVO for their valuable advice and guidance. On behalf GECCO, we would also like to thank Uber, Beacon and CINVESTAV-IPN for their sponsorship and support. Enjoy the conference! Carlos A.
