This is the 27th edition of the annual conference on all aspects of computing with constraints, including: theory, algorithms, environments, languages, models, systems, and applications such as decision making, resource allocation, scheduling, configuration, and planning. The Association for Constraint Programming has a list of previous conferences in this series.

The CP 2021 program will include presentations of high quality scientific papers on constraints technology. In addition to the usual technical track, the CP 2021 conference will feature thematic tracks. Each track has a specific sub-committee to make sure that competent reviewers will review the papers submitted by people of these domains.

Importantly, members of the Association for Constraint Programming are very sensible to the respect due to people attending the events organized by the association, as claimed in this policy. The ACP has an anti-harassment policy to ensure a harassment-free environment and will seek advice from the Faculty of Law of Montpellier if needed.
