Code of Conduct

SoCG is dedicated to providing an environment that is free from harassment, bullying, discrimination, and retaliation for all participants. All attendees, speakers, sponsors, and volunteers at our conference are required to agree with the CG Week code of conduct.

If an author has a conflict of such nature with a potential reviewer, and the author has sufficient grounds to believe that the review would be negatively biased, then the author is asked to declare this conflict in HotCRP. You are also welcome to contact a SoCG SafeTOC advocate who will treat any supporting information confidentially. For a list of SoCG advocates with contact information, please refer to CG Week Code of Conduct.

Submission Guidlines

  • 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
    For the first time, this year's 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, and email addresses should not appear at the beginning or in the body of 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 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. “Erin Chambers (Saint Louis University)”, “All (University of Sydney)”.) of other professional or personal conflicts. 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. Authors must use the new LaTeX class file socg-lipics-v2021.cls (version 0.9), with the option “anonymous”; note that the cls file is a wrapper around the standard LIPIcs class. The LIPIcs style and instructions are available here; the class file is available here, and instructions on how to use it are available here. 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.
  • 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 are any, in a repository accessible to the reviewers. Authors are asked to indicate which of the supporting materials will remain publicly available if their papers are accepted.
  • Previous or simultaneous submission
    Previous or simultaneous submissions 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 are available here.

Accepted Papers

  • Presentation, awards, and special issues
    An author of each accepted paper will be expected to attend the symposium and present the paper (approximately 20 minutes). Given the developing COVID-19 pandemic, the format of both attendance and presentation will be clarified closer to the event. Awards will be given for the best paper and for the best student presentation. Authors of a selection of 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. As in the previous years, the authors of the best paper will be invited to submit an extended version of their paper to Journal of the ACM.
  • 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.
