The Workshop attracted 50 participants from 12 different countries. The aim of this Workshop was to bring together researchers and practitioners in an informal but supportive environment to discuss current developments and future research directions in local search methods and their applications. The Workshop had diverse streams covering a range of techniques and case studies describing the use of local search in practice. There were two plenary sessions. Thomas. Stu¨tzle (Darmstadt University

He reviewed the ant colony approach and discussed its merits relative to other local search methods. Wim Nuijten (ILOG, France) presented an overview of constraint satisfaction and its relationship with local search methods, discussing advantages and disadvantages of constraint programming compared to local search. He also outlined a number of promising new research directions emphasizing the need to solve combinatorial optimization problems in practice. This issue contains sex papers on local search that were presented at the Workshop. We classify the papers into methodology, classical problems (in combinatorial optimization) and applications.
