====================================================================== CP2026 Workshop on Soft Constraints, Discrete Optimization, and Machine Learning (Soft 2026) July 24th, 2026 ISCTE, Lisbon, Portugal Held in conjunction with the Federated Logic Conference (FLoC'26) and 32th International Conference on Principles and Practice of Constraint Programming (CP 2026) https://hub.imt-atlantique.fr/soft2026 ******************************************** Paper Submission Deadline: May 15th ******************************************** ====================================================================== Call for Papers ====================================================================== This workshop aims to bring together researchers on constraint reasoning, optimization, and learning to present recent advances, share ongoing work, and discuss future directions for hybrid approaches that combine discrete optimization with machine learning and data mining. Topics of Interest (but are not restricted to): - Max-SAT - Max-SMT - Markov Random Field - Pseudo-Boolean Optimization - Soft global constraints - Weighted CSP - Integer Programming - Combining discrete optimization with machine learning for better solver design. - Data-driven strategies to guide search heuristics, branching, or propagation. - Using machine learning and data mining techniques to guide search. - Integrating deep neural networks to improve solvers. Submissions ----------- The aim of this workshop is to provide a forum where researchers currently working in this area can exchange their ideas, discuss new developments and explore possible future directions. Therefore, we welcome and encourage three types of submission: 1) Work in progress and Original work. Submissions of an extended abstract or a full paper, up to 15 pages in the LIPIcs format (https://submission.dagstuhl.de/series/details/LIPIcs#author), about unpublished ideas will be reviewed by a double-blind process and if accepted and the authors agree the final version will be made available on the workshop website. 2) Already published work. Authors who are interested in giving a presentation to the workshop's audience may submit their work non-anonymously while indicating where this work has been published. We will only accept work which has been published in the last calendar year (e.g., CPAIOR 2025, CP 2025, ECAI 2025, IJCAI 2025, AAAI 2026, and any journal or conference held after May 2025). 3) Papers not selected for the main CP conference. Decisions about acceptance of these papers will be based on their reviews. Contributions should be submitted in the form of a PDF file, following LIPIcs guidelines, using the link https://submissions.floc26.org/soft/ The type of submission as defined above should be clearly stated during the submission. At least one author of each accepted paper must attend the workshop. This workshop is open to all members of the FLoC community. All workshop participants must pay the workshop fee.
