CoNGA'25 invites original contributions on topics related to next generation arithmetic, specifically universal number (unum) and posit arithmetic, including, but not limited to:

• Posit & Valid Arithmetic
• Artificial Intelligence Data Formats
• Energy Efficient Arithmetic
• Right Sizing Precision

We also invite proposals for short reports and presentations/tutorials on the following topics:

• Posits libraries and other number coding libraries
• Hardware projects
• Exploring new applications
• New and interesting use cases
• Standarisation efforts
• Why mixed precision effort is a dead end

Authors are invited to submit manuscripts of original, unpublished research and recent development in next generation arithmetic (NGA).
The submitted manuscripts can be up to 16 pages, written in English and formatted according to the Springer’s LNCS format's templates without changing default margins, fonts, etc. .
Submissions will be accepted electronically via EasyChair.
Accepted manuscripts will be published as a part of Lecture Notes in Computer Science (LNCS) revised post-proceedings volume. CoNGA'24 volume can be found here.

Authors should use the proceedings templates, either for LaTeX or for Word, for the preparation of their papers. Supplementary materials that facilitate verification of the results, e.g., source code, proof details, etc., may be appended without a page limit or uploaded as separate files, but reviewers are neither required to read them nor will they be printed in the proceedings. Hence submissions must be complete, intelligible and self-contained within the 16 pages limit. Papers should have page numbers to facilitate their review. In LaTeX, this can be achieved for instance using\pagestyle{plain}. Each submission must be a single PDF file. Springer encourages authors to include their ORCIDs in their papers. Springer also offers a feature for the inclusion of embedded videos in proceedings papers.

In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made. Please refer to Information for Authors of Springer Computer Science Proceedings for additional information. Papers should present original research and should provide sufficient background material to make them accessible to the broader community. It should not be submitted in parallel to any other conference or journal. All manuscripts will be reviewed and judged on correctness, originality, technical strength, and significance, quality of presentation, and interest and relevance to the conference. At least one author of an accepted paper should preferably be available to present the paper at CoNGA'25 (14–15 November 2025, St. Louis, MO, US) in person.
