The two-volume set LNCS 10627 and 10628 constitutes the refereed proceedings of the 11th
International Conference on Combinatorial Optimization and Applications COCOA 2017 held in
Shanghai China in December 2017. The 59 full papers and 19 short papers presented were
carefully reviewed and selected from 145 submissions. The papers cover most aspects of
theoretical computer science and combinatorics related to computing including classic
combinatorial optimization geometric optimization complexity and data structures and graph
theory. They are organized in topical sections on network approximation algorithm and graph
theory combinatorial optimization game theory and applications.
