Programming, Artificial Intelligence, and Operations Research will be held
in Vienna, Austria, in the period July 5th-July 8th, 2021. The conference
will be a mixed virtual/actual conference assuming circumstances permit, or
a completely virtual conference otherwise.

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.
INSTRUCTIONS FOR REGULAR PAPERS
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. Authors should consult Springer's authors'
guidelines and use their proceedings templates, either for LaTeX or for
Word, for the preparation of their papers. Springer encourages authors to
include their ORCIDs in their papers. In addition, the corresponding author
of each paper, acting on behalf of all of the authors of that paper, must
complete and sign a Consent-to-Publish form. The corresponding author
signing the copyright form should match the corresponding author marked on
the paper. Once the files have been sent to Springer, changes relating to
the authorship of the papers cannot be made.
REVISED DUE DATES: Due to the late occurrence of CPAIOR2020 and a number of
requests we have pushed back the submission dates to give authors more time
to prepare their submissions. The new dates are given below.
Submission schedule for regular papers (both long and short):
Abstracts: January 21st, 2021 (anywhere on Earth: AoE)
Full papers: January 28th, 2021 (AoE)
Rebuttal Phase: February 25th-March 2nd, 2021
Notification: March 13th, 2021
Camera-ready version: March 27th, 2021 (AoE)
INSTRUCTIONS FOR EXTENDED ABSTRACTS
Extended abstracts should be 1 or 2 pages in length and may present
preliminary work or work already published in other outlets. The extended
abstracts are submitted for presentation only (if accepted), and will not
be formally published in the LNCS conference volume. A collection of the
accepted extended abstracts will be published on the conference website. A
submission representing work submitted or published in another outlet
should state that outlet. Extended abstracts will be reviewed to ensure
appropriateness for the conference.
Submission schedule for extended abstracts:
Abstract: March 3, 2021 (AoE)
Notification: April 4th, 2021
