COCOA 2025: Call for Papers

The 18th Annual International Conference on Combinatorial Optimization and Applications (COCOA 2025) will be held during November 28-30, 2025 in Tianjin, China. Original research papers in the areas of combinatorial optimization and its applications are solicited. In addition to theoretical results, the conference is particularly interested in submissions that report on experimental and applied research of general algorithmic interest. Special consideration will be given to research that is motivated by real-world problems. Experimental and applied papers are expected to show convincingly the usefulness and efficiency of the algorithms discussed in a practical setting.

The topics include, but are not limited to:

• Algorithms and Data Structures
• Approximation Algorithms
• Operation Research

• Notification of Decision: September 25, 2025
• Final Version Submission: October 10, 2025
• Author Registration Due: November 10, 2025
• Conference Dates: November 28-30, 2025

Paper Submission

The submission should contain a scholarly exposition of ideas, techniques, and results, including the motivation and a clear comparison with related work. The length of the submission should not exceed 12 pages in LNCS style (including references, but excluding the optional appendix). Springer’s proceedings LaTeX templates are available in Overleaf. Please make sure to hide all author-related information, as the conference will conduct a double-blind review process.

Submitted papers must describe work not previously published and must not be submitted simultaneously to any other conference with refereed proceedings or to journals. Only electronic PDF submission will be allowed via the Springer Online Conference System. Please submit your paper at https://easychair.org/conferences?conf=cocoa2025.

For the complete author guideline, please access Springer's official Springer_Instructions_for_Authors_of_Proceedings_CS.pdf.

Proceedings

The conference proceedings will be published by Springer-Verlag in the Lecture Notes in Computer Science series. After the conference, selected papers will be published in special issues of journals. Previous COCOA proceedings can be found through Previous COCOA Papers.

Awards

The Best Paper and the Best Student Paper will be awarded. A paper is eligible for the Best Student Paper if all authors are full-time students at the time of submission. To indicate that a submission is eligible, please add the phrase "Eligible for best student paper" as the last sentence in the "Abstract" field in the web form on the submission server as well as in the paper.
