Open Access Policy

This journal provides immediate open access to its content. No subscription is needed to access the articles, and no download fees are charged. Authors are not charged for publication in this journal, and the journal does not request any submission fee nor any article processing fee.

Copyright Policy

The authors retain the copyright and full publishing rights without restrictions.


We ask authors to confirm that, if their paper is accepted for publication, they will provide sufficient computer code and data for others to reproduce the results presented in their paper or provide justification for not providing this information (e.g., because of a non-disclosure agreement with a data source) and an alternative means of reproduction (e.g., a dataset of similar characteristics to that used in the paper and anonymized for public distribution and binaries executing their algorithm).

Short Papers

The authors have the possibility to submit short papers (no more than 8 pages using the journal template), for which the editorial board will do its best to provide a first answer within 3 months. Regular papers have no page limit.

Papers previously published in conference proceedings

Papers previously published in conference proceedings are welcome, provided that the authors inform the editorial board on this in the submission cover letter, highlight the novel parts in the new submission, and that the journal version contains significant extensions from the conference version.

Peer Review

Each manuscript is handled by one section editor and one associate editor. The manuscript might be assigned to a section editor different from the the one suggest by the authors, for instance to avoid conflicts of interest or to better balance the workload among the different section editors. Following the single blind review process, independent referees are asked to submit their assessment within two or three months after receiving the manuscript, and possibly more depending on the length of the article.

Licensing Policy

All content is licensed under the Creative Commons Attribution 4.0 International License so that interested researchers are free to remix, transform, and build upon the material for any purpose.

Privacy Statement

The names and email addresses entered in this journal site will be used exclusively for the stated purposes of this journal, and will not be made available for any other purpose or to any other party.

Publication ethics

The Open Journal of Mathematical Optimization adheres to the Code of Practice of the European Mathematical Society. In particular, the journal publishes original articles that have not been published elsewhere (preprints on institutional or public repositories do not count for this purpose). Any form of plagiarism implies rejection of the article and may be brought before the Ethics Committee of the EMS; this includes but is not limited to

  • outright plagiarism (presenting the work of other researchers, whole or in part, as one's own, either verbatim or rephrased);
  • self-plagiarism (presenting one's own previously published work, whole or in part, as novel);
  • deliberate replication of already known results and concepts, whole or in part, under new names or in new notation, without a appropriate reference and justification.

The journal is also committed to a transparent and fair peer review process. Any failure to uphold this standard by reviewers or editors should (with appropriate documentation) be immediately brought to the attention of the Managing Editor, who will investigate the claim and if necessary discuss further steps with the Steering Committee.


The authors of a published paper are free to deposit a copy of all versions of their paper in an institutional or other repository of their choice, incuding the submitted version, the accepted version, and the published version.

Publishing schedule
