Call for Papers

The 15th Annual International Conference on Combinatorial Optimization and Applications (COCOA 2021) will be held during December 17-19, 2021 in Tianjin, China. Original research papers in the areas of combinatorial optimization and its applications are solicited. In addition to theoretical results, we are 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

·       Communication Network Optimization

·       Energy Efficient Wireless Sensor Networks

·       Optimal Resource Management

·       Social Networks

·       Complex Network Optimization

·       Computational Algebra

·       Computational Geometry

·       Computational Biology

·       Computational Financing

·       Computational Game Theory

·       Computational Learning Theory

·       Computational Number Theory

·       Bioinformatics

·       Graph Theory

·       Graph Search

·       Distributed Computational Systems

·       Urban Transportation Networks

·       Mobile Ad Hoc Networks

·       Scheduling

·       Big Data

Paper Submission

The submission should contain 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 fifteen pages in LNCS style. Submitted papers must describe work not previously published. They must not be submitted simultaneously to any other conference with refereed proceedings or to journals. We regard the following case as a simultaneous submission. Submission of drafts which contain the essentially same results from papers under review in other conferences or journals at the moment of the submission. Only electronic submission will be allowed via the Springer Online Conference System. Submission link:



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: Theoretical Computer Science, Journal of Combinatorial Optimization, and Discrete Mathematics, Algorithms and Applications.


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.
