The Conference on Complex Systems (CCS) is the biggest and most important annual meeting of the international complex systems community. It comes under the auspices of the Complex Systems Society. From its inception in 2004 and until 2014, CCS had always been Europe-based, but in 2015, 2017 and 2019 it moved to North America, to Latin America and to Asia, respectively. In 2020, due to the Covid-19 pandemic, it was held as a fully online conference.
In 2021, CCS is back to Europe and will be held in Lyon, France, from October 25 to 29, 2021. As some travel restrictions might still apply, it is expected that the conference will take a hybrid form, with as many sessions and talks as possible happening at the venue, but with the possibility to participate and give contributions remotely.
