PAPER SUBMISSION (now identical for long and short papers):
Abstract due : JANUARY 19, 2011 11.59 P.M. PST
Paper due: JANUARY 26, 2011 11.59 P.M. PST
Notification: MARCH 02, 2011
Final version due: MARCH 16, 2011

The Eighth International Conference on Integration of Artificial Intelligence and Operations Research Techniques in Constraint Programming will be held in Berlin, Germany, May 23-27, 2011.

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 new 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. Finally, application papers showcasing CP/AI/OR techniques on innovative 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, Lagrangean and convex relaxations, heuristic functions based on constraint relaxation.

* Search methods: branch and bound, intelligent backtracking, incomplete search, randomized search, column generation and other decomposition methods, local search, meta-heuristics.

* Integration methods: static/dynamic problem decomposition, solver communication, transformations between models and solvers, collaboration between concurrent methods, models, and solvers.

* 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. PAPER SUBMISSION

Paper submissions are of two types: Long papers and short papers.

Long papers should present original unpublished work and be at most 15 pages plus references in length, and should be prepared in the format used for the Springer Lecture Notes in Computer Science series (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.

NOTE: Unlike previous CPAIOR conferences the page limit for long papers is 15 LNCS pages *plus references*.

INSTRUCTION FOR SHORT PAPERS: Short papers are also encouraged, limited to 5 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.

All papers are to be submitted electronically in PDF format by following the instructions at the URL
