Call for Problem Submission for the MiniZinc Challenge 2026
Jason Nguyen
The MiniZinc Challenge is an annual solver competition in the Constraint Programming (CP) community
held before the International Conference on Principles and Practice of Constraint Programming.
The MiniZinc Challenge 2026 is seeking interesting problem sets on which various constraint solving
technologies should be compared on this year. Everyone is allowed to submit problems regardless of
whether they are an entrant in the challenge.
- Problem submission open: now
- Problem submission deadline: Fri, 24 April 2026
There are no restrictions on the kind of problems, but ideally they should be of interesting nature such as practice-related problems and puzzles etc. Problem submissions with real-world instances are particularly welcome. We may need to make some modifications to submitted models to ensure they are in a format suitable for the challenge.
