Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.
  • The submission has not been previously published, nor is it before another journal for consideration (or an explanation has been provided in Comments to the Editor).
  • The submission file is in PDF document file format.
  • Where available, URLs for the references have been provided.
  • The authors understand that they must do the final typesetting, formatting, copyediting, and layout of their article themselves, using the journal's LaTeX class file.
  • The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines.

Author Guidelines

There are three main criteria for a successful submission. First, the results that are presented must be new and interesting. Second, the submission must be carefully prepared. Third, the topic should be within scope. Submissions that do not satisfy these criteria are likely to be rejected.

A guideline for the first criterion may be: do you think the paper is a worthwhile read for the readers of the journal? Does it add sufficiently much to the state of the art? If the results appeared in a conference proceedings before, then the submission must provide this information.

The second criterion, careful preparation, suggests that authors should provide a good structure, good illustrations, good layout, good language, consistent notation and choices, and so on and so forth. For example, if many figures are poor to the extent that the authors should have noticed this themselves, then a submission fails on the criterion of careful preparation. 

The third criterion, being within scope, is sometimes also subjective. We aim to be inclusive, and allow submissions that are not mainstream but still somewhat within scope. In these cases, the authors must make an effort to provide the link of their results with the scope of the journal.

COI Information

We use the following conflict-of-interest policy, roughly modeled on the policy of ACM publications at and the SafeTOC guidelines at

The following people are assumed to have a conflict of interest in reviewing each others' work:
- Close relatives, people in romantic or sexual relations with each other, and close personal friends
- Doctoral advisors and their students or former students
- People who have worked at the same institution or collaborated on joint publications or grants with each other within the last two years
- Any pair of people involved in accusations of sexual or workplace harassment, regardless of whether those accusations have been formally investigated
- Any notable or significant rivalry or animosity between research groups

Authors of submissions may specify conflicts of interest that might not be publicly known, in the cover letter to the editor. Details of why the conflict exists may be omitted, but in accordance with the SafeTOC guidelines, such claims may be checked with one of the ToC Advocates closely affiliated with the field. These specifications will otherwise be kept confidential. Potential conflicts of interest may also be identified by journal editors and reviewers at any step of the publication process, and should be reported to the editor handling the submission or the editors in chief as appropriate.

To the extent possible, people with conflicts of interest should not serve as editors or reviewers for submissions by people they have conflicts with. In cases where conflicts are unavoidable, they should be reported to the editors in chief. In cases where all editors in chief have a conflict with a submission, they will designate another member of the editorial board to perform the functions of the editors in chief for that submission.

Authors, editors, and reviewers may also have a conflict of interest with respect to the content of submissions, for instance when the research involves the potential for financial gain by the author, editor, or reviewer, a close associate or family member, or when they are receiving compensation or grant funding from a company that would benefit from the publication of the research. All such conflicts involving authors must be declared in both the submitted and published versions of the papers. Editors and reviewers should not handle papers with which they have a conflict of this type, just as if they had a conflict with the author.

Serious violations of this policy may result in referrals to professional boards such as the ACM Committee on Professional Ethics or to the employers of the people involved in the violation.
