The Author Guidelines will also include IOPP’s recommendations, such asmultiple authorship.As a general rule we would advise that an author does not submit more than two articles to a conference. This includes papers that they have co-authored. Our guidance on what constitutes authorship is available on: https://publishingsupport.iopscience.iop.org/questions/ethics-of-authorship/

Peer Review Reports: Reviewers must give a clear statement of recommendation for each paper. Comments must be included to support their recommendation. These comments should be suitable for transmission to the author. Editors and organizers shall only accept papers where there is clear support from the reviewers. The comments can be written on the platform in the free-text box or can be attached to the papers.

Similarity: We recommend a maximum similarity of 30% and would encourage authors to include their references when checking the similarity score. The Proceedings Editors will be able to check the score and type of reuse in more detail during the assessment stage including the references and bibliography. We understand that there are valid reasons for higher similarity, for example, for literature reviews.

Generative AI Tools: There are many responsible and appropriate uses for generative AI within scholarly research and we support authors using it in this manner. When doing so, authors are encouraged to be transparent about their use of any generative AI tools in either the research or the drafting of the manuscript. Authors are also encouraged to maintain records of previous drafts, as well as any prompts used in the editing or generation of material within their manuscript. Please state this in the Acknowledgements of the paper.
