This ebook constitutes the refereed court cases of the fifth foreign convention on Combinatorial Optimization and functions, COCOA 2011, held in Zhangjiajie, China, in August 2011. The forty three revised complete papers have been conscientiously reviewed and chosen from sixty five submissions. The papers disguise a extensive variety of issues in combinatorial optimization and functions focussing on experimental and utilized learn of common algorithmic curiosity and learn stimulated by way of real-world problems.
