During this year 2020, and for the first time in the history of the series of Conferences sponsored by the Complex Systems Society, the CCS series, the annual meeting was organized virtually in the period December 7-11, 2020 and the young researchers CCS2020 Warm Up sessions on December 4, 2020. This Conference is in line with the series of meetings previously held in Singapore (2019), Thessaloniki, Greece (2018), Cancun, Mexico (2017), Amsterdam, Netherlands (2016), Tempe, Arizona, USA (2015), Lucca, Italy (2014), and more meetings in previous years. All these past meetings have delivered the highest quality of presentations, the most up-to-date findings, have been attended by the pioneers in the field of Complex Systems, as well by young aspiring students, numbering an attendance of close to one thousand. Our purpose is to deliver a well-tailored and focused event of the highest scientific and organizational standards, and for the first time in this online mode. We all for sure missed the warmth and cordiality that has been the tradition of past CCS meetings, but in view of the current world situation we were forced to this unprecedented step of meeting online. We all hope that next year we will return to the classical physical meetings that we all know.
This year’s meeting was organized by the Aristotle University of Thessaloniki in Greece. It was attended by ~600 scientists from ~60 different countries spanning ~18 different time zones. It comprised of four (4) full days of 17 plenary and invited presentations, and ~350 contributed oral, ignite, and poster presentations. Additionally, there was one (1) day of 16 satellite meetings, with over ~100 presentations. Here in this volume are given the abstracts of these presentations in the four regular days.
Furthermore, during this annual meeting we had some exciting special sessions that attracted interest. These included a presentation of journals from the European Physical Society and other publishers that specialize in Complexity topics. A session was given on funding opportunities by the European Commission. A round-table discussion took place with the subject of Covid-19 and Complexity. Finally, the annual presentation of awards took place, to honor members of our community who have given outstanding contributions to our field. Due to the online mode of presentations all events were recorded and are available to all participants.
