Call For Papers
The 16th International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research will be held in Thessaloniki, Greece, June 4 – 7, 2019.

The aim of the conference is to bring together interested researchers from Constraint Programming (CP), Artificial Intelligence (AI), and Operations Research (OR) to present new techniques or 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 also to give these researchers the opportunity to show how the integration of techniques from different fields can lead to interesting results on large and complex problems. Therefore, papers that actively combine, integrate, or contrast approaches from more than one of the areas are especially solicited. High quality papers from a single area are also welcome, if they are of interest to other communities involved. Application papers showcasing CP/AI/OR techniques on novel and challenging applications or experience reports on such applications are strongly encouraged.

The program committee invites submissions that include but are not limited to the following topics:

    Inference and relaxation methods: constraint propagation, cutting planes, global constraints, graph algorithms, dynamic programming, Lagrangian and convex relaxations, heuristic functions based on constraint relaxation.
    Search methods: branch and bound, intelligent backtracking, incomplete search, randomized search, portfolios, column generation, Benders decompositions or any other decomposition methods, local search, meta-heuristics.
    AI and Machine Learning techniques applied to solve optimization and Operations Research problems.
    Integration methods: solver communication, model transformations and solver selection, parallel and distributed solving, combining machine learning with combinatorial optimization.
    Modeling methods: comparison of models, symmetry breaking, uncertainty, dominance relationships.
    Innovative applications of CP/AI/OR techniques.
    Implementation of CP/AI/OR techniques and optimization systems.

Submissions are of two types: regular papers (submitted for publication and presentation) and extended abstracts (submitted for presentation only). Outstanding regular paper submissions may be invited to be published directly in the journal Constraints through a ‘fast track’ process.

This year’s conference will, as last year, give a distinguished paper award and a student paper award.


Regular papers should present original unpublished work and can be of two types:

    long papers (at most 15 pages plus references)
    short papers (at most 8 pages plus references)

Both long and short papers will undergo rigorous review and are subject to the same criteria of quality. Both types are also eligible for distinguished paper or student paper award. Short papers are particularly encouraged for interesting and novel work in progress, for which the practical or theoretical relevance is not yet fully identified.

The conference proceedings will be published in the Springer Lecture Notes in Computer Science series. All regular papers should be prepared in the format used for that series (
