Annual Conference on Complex Systems (ECCS or CCS)
Since 2004, the Conference on Complex Systems organized by the CSS, is the most important annual meeting for the complex systems research community. Until 2014, it was the European Conference on Complex Systems. In 2015, it became CCS with its first "global" edition in the USA. In 2016, CCS came back to Europe and took place in Amsterdam, Netherlands.
The CCS steering committee, elected among the members of the Complex Systems Society, is responsible for the development and support of the CCS conference series.
