Scope
-----
Algebraic and coalgebraic methods and tools are a mainstay of computer
science. From data types to development techniques and specification
formalisms, both theoreticians and practitioners have benefited from
the large body of research proposed and implemented since the
pioneering works of the 1960s.

CALCO aims to bring together researchers with interests in both
foundational and applicative uses of algebra and coalgebra in
computer science, traditional as well as emerging ones

CALCO is a high-level, bi-annual conference formed by joining the
forces and reputations of CMCS (the International Workshop on
Coalgebraic Methods in Computer Science) and WADT (the Workshop on
Algebraic Development Techniques). Previous CALCO editions took place
in Salzburg (Austria, 2021), London (UK, 2019), Ljubljana
(Slovenia,2017), Nijmegen (the Netherlands, 2015), Warsaw (Poland,
2013), Winchester (UK, 2011), Udine (Italy, 2009), Bergen (Norway,
2007), Swansea (Wales, 2005).

The 10th edition will be held in Bloomington, Indiana, co-located with
MFPS XXXIX. It is planned as a physical, in-person event, with
support for remote presence, both for speakers and for other
participants who are unable or unwilling to travel.


Submission Categories
---------------------
CALCO invites papers relating to all aspects of algebraic and
coalgebraic theory and applications, and distinguishes between four
categories of submissions.

1. Regular papers that report
* results on theoretical foundations
* novel methods and techniques for software development
* experiences with technology transfer to industry.

2. (Co)Algebraic Pearls papers that
* present possibly known material in a novel and enlightening way.

3. Early ideas abstracts that lead to
* presentations of work in progress
* proposals for original venues of research.

4. Tool presentation papers that
* report on the features and uses of algebraic/coalgebraic tools.

Submissions Guidelines
----------------------
All submissions will be handled via EasyChair:
https://easychair.org/conferences/?conf=calco2023

The format for all submissions is specified by LIPIcs. Please use the
latest version of the style:
http://www.dagstuhl.de/en/publications/lipics/instructions-for-authors/

It is recommended that submissions adhere to that format and length.
Submissions that are clearly too long may be rejected immediately.


Regular papers
--------------
Prospective authors are invited to submit full papers in English
presenting original research. Submitted papers must be unpublished and
not submitted for publication elsewhere. Regular papers should be
maximum 15 pages long, excluding references. Proofs omitted due to space
limitations may be included in a clearly marked appendix.

Proceedings will be published in the Dagstuhl LIPIcs Leibniz
International Proceedings in Informatics series.

A special issue of the open access journal Logical Methods in Computer
Science (http://www.lmcs-online.org), containing extended versions of
selected papers, is planned.


(Co)algebraic pearls
--------------------
This is a recent submission category. Explaining a known idea in a new
way may make as strong a contribution as inventing a new idea. We
encourage the submission of pearls: elegant essays that illustrate an
idea in a beautiful or didactically clever way, perhaps by developing
an application. Pearls are typically short and concise and so should
not be longer than regular papers in the format specified by
LIPIcs. Authors who feel they need a bit more space should consult
with the PC co-chairs. The accepted papers will be included in the
final proceedings of the conference. Each submission will be evaluated
by at least two reviewers.


Early ideas abstracts
---------------------
Submissions should not exceed 2 pages in the format specified by LIPIcs.
The volume of selected abstracts will be made available on arXiv and on
the CALCO pages. Authors will retain copyright, and are also encouraged
to disseminate the results by subsequent publication elsewhere. Each
submission will be evaluated by at least two reviewers.


Tool papers
-----------
Submissions should not exceed 5 pages in the format specified by LIPIcs.
The accepted tool papers will be included in the final proceedings of
the conference. The tools should be made available on the web at the
time of submission for download and evaluation. Each submission will be
evaluated by at least three reviewers, and one or more of the reviewers
will be asked to download and use the tool.


Best Paper and Best Presentation Awards
---------------------------------------
This edition of CALCO will feature two awards: a Best Paper Award whose
recipients will be selected by the PC before the conference and a
Best Presentation Award, elected by the participants.
