The journal is devoted to advance and promote the theory and applications of combinatorics and optimization as well as interdisciplinary. It is aimed to publish original high quality refereed papers, occasionally survey articles and short notes. There are no fees for submitting, processing, or publishing an article in Communications in Combinatorics and Optimization CCO publishes 2 issues annually, the first issue at the end of June and the second issue at the end of  December. 

The journal is indexed by MathSciNet and zbMath.  


We are delighted to announce that Communications in Combinatorics and Optimization is indexed by Scopus now. Content are expected to be available in Scopus soon. We will activate the link as soon as possible.
