The Association for Constraint Programming invites proposals for organizing the ACP Summer School on Constraint Programming in 2027. Since its establishment, the summer school has been a major success with feedback from student attendees being very positive.

The proposed topic of the school can be on general CP or on a specific research subject. A complete list of ACP summer schools can be found here: http://www.a4cp.org/events/summer-schools

Members of the CP community who are interested in organizing the 2027 Summer School should send a proposal to helene.verhaeghe@uclouvain.be by the 31st of August 2026, covering the following aspects:

  • topic of the school
  • location (and possible co-locations)
  • dates
  • organizers
  • tentative list of speakers
  • provisional budget

Co-location with related summer schools, such as those organised by SAT or ICAPS, will be viewed favorably.
