### Focus and Scope

The Journal of Computational Geometry (JoCG) is an international open access electronic journal devoted to original research of the highest quality in all aspects of computational geometry. JoCG publishes papers on the design and analysis of geometric algorithms, the complexity of geometric problems, experimental work on geometric algorithms, applications of computational geometry, and topics at the intersection of geometry and algorithms. Topics include metric space embeddings, graph drawing, computational topology, topological learning, topological combinatorics, meshing, compressed sensing, manifold learning, computer-aided design, discrete geometry, and combinatorial geometry. Outstanding survey papers in the area are also considered.

### Peer Review Process

After an initial screening process, each submission to JoCG is assigned to an editor who will ensure that the submission is refereed. Submissions are judged based on relevance, foundational/conceptual contribution, technical contribution, relation to open problems, and community interest. Reviewers, who are chosen based on their expertise, are asked to complete their reviews within 8 weeks, though exceptions may be made for particularly long and/or technical submissions. (See these statistics for actual review times.) Reviewers and editors are asked to make decisions based on the following guidelines:

*Submissions to JoCG should be judged based on their relevance, foundational/conceptual contribution, technical contribution, relation to open problems, and community interest**. (Further information about these criteria can be found here.) To be accepted into JoCG, a paper should be rated highly in several of the above measures. *

*For comparison purposes, the quality of research in a JoCG article should be similar to what one would expect to find in a typical SoCG (Symposium on Computational Geometry) or SODA (ACM-SIAM Symposium on Discrete Algorithms) paper. This is not to say that only papers acceptable to SoCG or SODA will be accepted by JoCG. Some types of papers (e.g., surveys, expository papers, and long technical contributions) that are not be suitable for a conference could still find a home in JoCG. *

*In addition, articles to appear in JoCG should meet the usual requirements of high-quality research articles. Articles should be well-written. Articles should include a thorough and complete discussion of related previous work. Technical details should be explained in full detail and as clearly as possible.*

*Failing to meet any of the above requirements is grounds for rejection or a request for resubmission. JoCG is a non-commercial enterprise and has no quotas on the numbers of papers that are accepted in any given time frame.*

### Publication Frequency

Individual articles are assigned volume, issue, and page numbers and published online immediately upon approval of the final camera-ready version. Volumes are finalized once per year.

### Open Access Policy

This journal provides immediate open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge.

### Archiving

This journal utilizes the LOCKSS system to create a distributed archiving system among participating libraries and permits those libraries to create permanent archives of the journal for purposes of preservation and restoration.

The publisher perpetually authorizes LOCKSS members to archive and restore Journal of Computational Geometry through the LOCKSS system.

In addition to LOCKSS conformance, JoCG is a registered data provider with the Open Archives Initiative, and implements the OAI-PMH protocol.

### Freedom

JoCG is a free (*libre* and *gratis*) open-access journal.

JoCG is *gratis* for authors: Authors of papers accepted to JoCG do not pay publication fees of any kind.

JoCG is *libre* for authors: Authors of papers accepted to JoCG retain the copyright to their work. Authors license their work to JoCG under a Creative Commons Attribution License. Authors are free to reuse, republish, and redistribute their work, with an acknowledgement of its initial publication in JoCG.

JoCG is *gratis* for readers: The contents of JoCG are available for download to the general public free of charge.

JoCG is *libre* for readers: The contents of JoCG are made available under a Creative Commons Attribution License. The contents of JoCG may be shared with others, reused, and redistributed, with an acknowlegdement of its authorship and initial publication in JoCG.

The price of freedom: Freedom requires that ongoing operating costs remain minimal. JoCG uses free open-source journal management software that runs on hardware and has internet access donated by the editors' home institutions. JoCG does not employ typesetters, proofreaders, layout editors, or copy editors. Instead, authors take full responsibility for the appearance of the final published version of their work.

### Review Criteria

The following review criteria are considered by editors and referees when reviewing a JoCG submissions. A paper that appears in JoCG should be rated highly on several of the criteria below. Note that these criteria apply to both theoretical or applied/engineering/experimental papers.

**Paper type**

Is the paper a

- first step (opens a new area)?
- last step (closes an important area)?
- giant step (makes essential progress)?
- none of the above?

Is the paper

- a theoretical contribution?
- an experience paper/experimental paper?
- an applied paper that shows an interesting application of geometric algorithms and concepts to other fields?
- or a combination of some of the above?

**Relevance**

In what respect is the paper relevant to the scope of JoCG? Is it directly relevant for the design, use, analysis, or implementation of algorithms for geometric problems? May it have indirect implications for the complexity of geometric problems?

**Foundational/conceptual contribution**

Does the paper introduce a new model, new notion, new definition, new approach, novel implementation, or a novel application? Note the significance and reasons for this novelty or note the absence of such a novelty.

**Technical contribution**

Does the paper make

- an introduction of a new technique?
- a novel use of known technique?
- a talented use of known technique?
- a traditional use of known technique?
- a trivial use of technical knowledge?

**Relation to open problems**

Does the paper solve completely/partially an open question? How important is this question? Is the question central/important/interesting/legitimate/stupid?. How much effort has been invested in solving it and by whom?

**Community interest**

Is the paper potentially interesting to the whole community, to a major field (e.g., meshing), to everyone in a restricted area (e.g., pseudotriangulations), or interesting only to the authors?

### The Editorial Process

When a paper is submitted to JoCG, the following events occur:

- The managing editors are notified that a new submission has been received.
- The managing editors decide to either reject the submission outright (for example if the submission obviously falls outside the scope of JoCG) or assign the submission to an appropriate editor.
- The editor assigned to the submission implements the usual peer review process for the submission and reaches a decision.
- The managing editors ensure that the editor's decision is reasonable with respect to the reviews received for the submission.
- In case the submission is accepted, the managing editors obtain a final camera-ready version of the submission from the authors and publish this version in the current issue.

### Publication Ethics and Malpractice Statement

JoCG follows the COPE Code of Conduct (2008). As part of this, we have the following policy with regards to confidentiality and conflicts of interest in the editorial process.

Submitted papers are *confidential*. Editors and reviewers are not supposed to distribute them, or use them for their own research. Reviewers identities are to remain anonymous, unless specifically authorized otherwise by the reviewer.

Editors and reviewers may have a personal bias on some papers. The reasons are many—personal/professional ties to authors, working on the same problem, etc. Editors and reviewers are asked to decide for themselves whether they have such a bias,. If so, reviewers should disclose this to the editor they are reviewing for. Editors should discuss this with the Managing Editors.
