Padova, Italy

June 5 - June 8, 2017


CPAIOR 2017, the Fourteenth International Conference on Integration of Artificial Intelligence and Operations Research Techniques in Constraint Programming, will be held in Padova, Italy, June 5 - June 8, 2017. A Master Class on Computational Techniques for Combinatorial Optimization on June 5, and the Main Conference on June 6 - June 8, 2017.

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 in combinatorial optimization 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, provided that 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, meta­heuristics.
  • Integration methods: solver communication, model transformations and solver selection, parallel and distributed resolution techniques, models, and solvers.
  • Modelling 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.

The proceedings of the conference will be published on the Lecture Notes on Computer Science series.

Important Dates

Submission Schedule (for both long and short papers):

  • Abstracts: November 16, 2016
  • Long Papers: November 22, 2016
  • Short Papers: November 25, 2016
  • Rebuttal Phase: December 23-28, 2016
  • Final notification: January 16, 2017
  • Camera-ready version: February 10, 2017

All deadlines are intended until 23:59 UCT-12: for example, if it is still November 16 anywhere in the world, then you can still submit an abstract.

Registration Deadlines:

  • Early: April 15, 2017
  • Regular: May 31, 2017

Conference Schedule:

  • Master Class: June 5, 2017
  • Main Conference: June 6-8, 2017


Paper submissions are of two types:

  • Long papers (15 pages, plus references)
  • Short papers (8 pages, plus references)

Long papers should present original unpublished work and be at most 15 LNCS pages plus references in length, and should be prepared in the format used for the Springer Lecture Notes in Computer Science series. These papers will undergo rigorous review. The proceedings will be published in the Springer Lecture Notes in Computer Science series.

Short papers are also encouraged, limited to 8 LNCS pages plus references and should be prepared with the same format as long papers. Although containing less material, short papers should describe original unpublished work and will be reviewed to the same criteria of quality as long papers. It is also encouraged to submit short papers about work in progress on ideas that are interesting but for which the practical or theoretical relevance is not yet fully identified. Short papers will be presented at the conference and published in the conference proceedings.

Additionally, outstanding submissions to the technical program will be offered the opportunity to be published exclusively through a fast track process in the Constraint Journal. Journal fast track paper will still be regularly presented at the conference.
