International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research



17th International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research, 2020, Vienna, Austria.  Co-located with SoCS 2020: The 13th Annual Symposium on Combinatorial Search

This conference will be preceded by a Master Class on Recent Advances in Optimisation Paradigms and Solving Technology.

Program Chairs: Emmanuel Hebrard and Nysret Musliu

Conference Chair: Nysret Musliu

Update: Due to COVID-19 the conference is rescheduled to take place in autumn 2020.


The aim of the CPAIOR conference series is to bring together interested researchers from Constraint Programming (CP), Artificial Intelligence (AI) and Operations Research (OR) to present new techniques or new applications, and to provide an opportunity for researchers in one area to learn about techniques in the others.  A main objective of this  conference series is to give researchers the opportunity to show how the integration of techniques from different fields can lead to interesting results on large and complex problems.

Typically, papers presented at CPAIOR actively combine, integrate, or contrast approaches from more than one of the areas.  High quality papers from a single area are usually also welcome.  Finally, application papers  showcasing CP/AI/OR techniques on innovative and challenging applications or experience reports on such applications have been strongly encouraged.

After a successful series of five CPAIOR international workshops in Ferrara (Italy), Paderborn (Germany), Ashford (United Kingdom), Le Croisic  (France), and Montreal (Canada), in 2004 CPAIOR became a conference with the first meeting held in Nice (France) with more than 100  participants.  In the subsequent years, CPAIOR was held in Prague (Czech  Republic), Cork (Ireland), Brussels (Belgium), Paris (France), Pittsburgh (USA), Bologna (Italy), Berlin (Germany), Nantes (France), Yorktown Heights, NY (USA), Cork (Ireland), Barcelona (Spain), Banff (Canada), Padova (Italy), Delft (Netherlands), and Thessaloniki (Greece), while the upcoming meeting takes place in Vienna (Austria).

Proceedings of this peer-reviewed conference are usually published in the Springer Lecture Notes in Computer Science series.  In some cases, a selection of papers is published in a special issue of a journal after another round of reviewing.  This has been standardized in recent years via a Journal Fast-Track reviewing process.  CPAIOR is indexed by DBLP and Google Scholar.
