CODE OF CONDUCT
SoCG is dedicated to providing an environment that is free from harassment,
bullying, discrimination, and retaliation for all participants. Starting in
2025, CG Week including SoCG will be organized as an event of the CG
Society (https://computational-geometry.org/society/). All members of the
Society are bound by its Code of Conduct. Only members of the Society can
give a presentation and hence at least one author of each accepted paper
must become a member of the Society. Society membership is free.
SUBMISSION GUIDELINES
+ Paper types
When writing or evaluating a SoCG paper, it is important to keep in mind
that there are different types of contributions, each with its own
strengths. To ensure that a submission is evaluated on its own merits,
authors will need to identify the main strengths of their submission, as
captured by four possible paper types. PC members and external reviewers
will be asked to take into account these paper types together with their
associated evaluation criteria when they evaluate a paper. There are no
quotas for the paper types and submissions can be labeled with more than
one paper type at the time of submission.
- Mathematical Foundations: A typical paper will contain theorems and
proofs describing new results in discrete or combinatorial geometry,
discrete differential geometry or topology, or in topological
combinatorics. The paper will primarily be evaluated on its technical
depth, the importance of the results, the elegance of the solution, the
connection of the problem studied to computational geometry and topology,
and the potential future impact on algorithm development.
- Algorithmic Complexity: A typical paper will contain algorithms, data
structures, theorems, proofs, or lower bound constructions describing new
results on computational geometry problems. The paper will primarily be
evaluated on the (mathematical or computational) relevance and importance
of the problem studied, its technical depth, the elegance of the solution,
and the potential future impact of the results or the proposed new methods
and techniques.
- Experiments and Implementation: A typical paper will make a clear
contribution to the implementation and evaluation of geometric algorithms,
such as exact, approximate, or algebraic computation, algorithms
engineering, or the experimental evaluation of competing algorithmic
approaches. The paper will primarily be evaluated on the completeness and
the expected impact of the proposed implementation, the soundness of the
experiments, the quality and quantity of testing, and on the general amount
of knowledge gained.
- Applications: A typical paper will describe the modeling and
algorithmic choices made when developing or adapting computational geometry
techniques for an application area. The paper will be primarily evaluated
on the soundness of the modeling decisions, the ingenuity of the solution,
the effectiveness of the proposed method, and the expected impact in the
application area. One might also consider the lesson learned regarding the
applicability or suitability of computational geometry tools to the
specific area.
+ Double Blind and PC submissions
SoCG will employ a lightweight double-blind reviewing process, and will
allow PC members (other than the PC chairs) to submit to the conference as
well. Submissions should not reveal the identity of the authors in any way.
In particular, authors' names, affiliations, funding information, and email
addresses should not appear in the submission. Authors should ensure that
any references to their own related work is in the third person (e.g., not
"We build on our previous work ..." but rather "We build on the work of
..."). Particular care needs to be taken if there is any accompanying
software or data, which needs to be linked anonymously (for example, via a
DropBox anonymous folder or Anonymous GitHub, perhaps with a subset of
synthetic data if the real data is not anonymized). Upon registering a
submission, the authors will declare conflicts of interest with PC members,
as well as listing email address or domain level conflicts (i.e. "Haitao
Wang (University of Utah)", "All (Graz University of Technology)") of other
professional or personal conflicts. This includes past advisors and
students, people with the same affiliation, and any recent/frequent
coauthors and collaborators. Please refer to the SoCG 2025 Conflict of
Interest Guidelines (
https://docs.google.com/document/d/1QNR3JUe_DimGP79EbcmayUi7I3obiTdxAIzXMFxaCfI/pub)
for a detailed discussion of possible conflicts of interest.
The purpose of lightweight double-blind reviewing is to help PC members and
external reviewers come to an initial judgment about the paper without
bias, not to make it impossible for them to discover the authors if they
were to try. Authors should feel free to disseminate their ideas or draft
versions of their paper as they normally would. For example, authors may
post drafts of their papers on the web, submit them to arXiv, and give
talks on their research ideas. We encourage authors with further questions
on double-blind reviewing to contact the PC chairs, or to see the more
detailed discussion in the proposal that preceded the vote to move to
double blind.
+ Format
Submissions must be formatted in accordance with the LIPIcs proceedings
guidelines (https://www.dagstuhl.de/en/publishing/series/details/lipics).
Authors are required to use the LaTeX class file socg-lipics-v2021.cls
(V0.9, Sep 19, 2022), with the option "anonymous"; note that the class file
is a wrapper around the standard LIPIcs class. The LIPIcs style and
instructions are available here (
https://submission.dagstuhl.de/series/details/5#author); the SoCG class
file is available here (
https://computational-geometry.org/documents/socg-lipics-v2021.cls), and
instructions on how to use it are available here (
https://computational-geometry.org/documents/linecount_2022_09_19.pdf).
Submissions must not exceed 500 lines, excluding front matter (title),
references, and a clearly marked appendix (further described below), but
including all other lines (in abstract, algorithms, tables, captions,
etc.). The class files provide line counting which should be accurate in
most cases. Authors should refrain from putting excessive amounts of text
in parts in which lines are not counted automatically. If authors need
constructs that contain uncounted lines of text, they should compensate for
this by reducing the final line count accordingly. It is the sole
responsibility of the authors not to exceed 500 lines even if some lines
are not counted automatically.
+ Contents of the submission
Papers should be submitted in the form of an extended abstract, which
begins with the title of the paper, as well as a short abstract. This
should be followed by the main body of the paper that begins with a precise
statement of the problem considered, a succinct summary of the results
obtained (emphasizing the significance, novelty, and potential impact of
the research), and a clear comparison with related work. The remainder of
the extended abstract should provide sufficient details to allow the
program committee to evaluate the validity, quality, and relevance of the
contribution. Clarity of presentation is very important; the entire
extended abstract should be written carefully, taking into consideration
that it will be read and evaluated by both experts and non-experts, often
under tight time constraints.
In addition, authors are asked to avoid "et al." in citations in favor of
an equal mention of all authors' surnames. For instance, if the number of
authors is large, consider writing "The authors in [#] show" instead of "A
et al. [#] show".
+ Appendix and additional data
All details needed to verify the results must be provided. Supporting
materials, including proofs of theoretical claims and experimental details,
that do not fit in the 500-line limit should be given in an appendix. If
more appropriate, the full version may be given as the appendix. In both
cases, however, the authors should include in the main part specific
pointers to the relevant locations in the appendix. The appendix will be
read by the program committee members and subreviewers at their discretion
and will not be published as part of the proceedings. Thus, the paper
without the appendix should be able to stand on its own. Experimental and
implementation results (independent of paper type) must be reproducible and
verifiable. Authors of all types of papers are encouraged to put
accompanying software and relevant data, if there is any, in a repository
accessible to the reviewers.
+ Previous or simultaneous submission
Results previously published or accepted for publication in the proceedings
of another conference cannot be submitted. Simultaneous submissions of the
results to another conference with published proceedings are not allowed.
Exempted are workshops and conferences without formal proceedings, but
possibly with handouts containing short abstracts. In particular,
submissions of papers that have appeared or will be submitted to EuroCG are
allowed, since EuroCG does not publish formal proceedings, while
submissions of papers that have appeared in CCCG are not allowed. Results
that have already been accepted (with or without revision) for publication
in a journal at the time of their submission to the symposium are not
allowed.
+ Strict guidelines
Submissions deviating from the above guidelines risk being rejected without
further consideration.
+ Guidelines for reviewers
The guidelines for reviewers are available here (
https://computational-geometry.org/documents/socg-reviewing.pdf).
ACCEPTED PAPERS
+ Presentation: An author of each accepted paper is expected to attend the
symposium and present the paper (approximately 20 minutes). Note that SoCG
2025 will be organized as an event of the CG Society (
https://computational-geometry.org/society/) and hence the presenting
author(s) must be a member of the Society. Society membership is free.
+ Best paper award: An accepted paper may be selected as the best paper.
All papers are eligible.
+ Best student paper award: An accepted paper may be selected as the best
student paper. A paper is eligible if all authors are students at the time
of submission. This must be indicated in the submission process. There is a
box provided for this purpose on the submission server.
+ Best student presentation award: Based on the feedback from the audience,
a presentation during the symposium by a student may be selected as the
best student presentation.
In exceptional cases, each of these awards may be granted to more than one
paper/presentation.
+ Invited papers and special issues: Authors of the best paper will be
invited to submit an extended version of their paper to the Journal of the
ACM, and authors of one (or more) most highly ranked papers may be invited
to submit their full paper to the journal TheoretiCS. Authors of a
selection of accepted papers from the symposium will be invited to submit
extended versions of their papers to special issues of Discrete &
Computational Geometry and Journal of Computational Geometry.
+ Format: Final proceedings versions of accepted papers must respect the
same formatting constraints as the submissions (LIPIcs proceedings format
with socg-lipics-v2021; 500-line limit, excluding front matter and
references), but must not comprise any appendix. If any supporting material
(including complete proofs of theoretical claims and experimental details)
does not fit in the specified limit, then the full version of the paper
containing this information must be referenced in the conference version
and made available at a public repository, such as arXiv, by the time the
final version is submitted. Where applicable, we encourage the authors to
make accompanying software and/or data publicly accessible, with proper
references in the paper.
