General Information

TheoretiCS is a Diamond Open Access electronic journal covering all areas of Theoretical Computer Science (TCS). TheoretiCS strives for top scholarship in Theoretical Computer Science, broadly construed. We invite submissions of original research papers of the highest quality. Papers are hosted on the Computing Research Repository (CoRR) on arXiv and are available in open-access. There are no publication charges for authors.


Submitted papers must be prepared in LaTeX using the TheoretiCS style, and must be written in English. The abstract length should preferrably be at most half a page, and no more than one page. Articles submitted to TheoretiCS must not have been already published at another academic journal or be under consideration for publication.

Submission process

First, the article should be posted to CoRR, via the usual arXiv submission process (providing the LaTeX source code of the article). Once the preprint has been published on CoRR, the paper can be submitted to the journal. If you cannot submit through arXiv, please contact the Editors in Chief.

Upon submission, authors must select a handling editor. Please choose an editor from the editorial board who works in a relevant field and is not in conflict of interest.


TheoretiCS follows a two-phase peer-reviewing process. In the first phase, the Editorial Board, possibly after seeking the opinion of external experts, decides whether or not a submission qualifies for a thorough review. The main criteria are the significance and lasting value of the results, the belief that the exposition is of high quality or will be after revision, and the availability of expert reviewers. Reviewers are asked to explicitly state whether they believe that the contribution of the submission is among the strongest contributions in its area in the last year or so.

TheoretiCS strives to conclude the first phase of reviewing and notify the authors about its result within three months. As of early 2023, a decision for the first phase was sent to the authors within 94 days after submission for 85% of the papers; the average was 64 days after submission.

In the second phase, reviewers check the validity and make suggestions to achieve a presentation of high quality. Submissions that qualify for the second phase are expected to eventually be published, usually in revised form, unless significant issues are detected or the desired quality of exposition is not achieved.
