The book "Experimental Algorithms" documents the refereed proceedings of the 14th International Symposium on Experimental Algorithms, which took place in 2015 in Paris. It includes 30 revised full texts selected from 76 submitted papers. The focus of the symposium is on the importance of experiments and algorithmic engineering techniques in the design and evaluation of algorithms and data structures. The contributions are divided into thematic sections that address various aspects such as data structures, graph problems, combinatorial optimization, scheduling and allocation, as well as transportation networks. This specialized book is aimed at professionals and students in the field of computer science and algorithms who are interested in the latest developments and techniques in experimental algorithmics.
