Special Session on Multicriteria Optimization using Nature-Inspired Metaheuristics in the Multicriteria Analysis and Optimization cluster at the 2010 ALIO-INFORMS International Meeting, Buenos Aires, June 6-9, 2010 Many practical search and optimization problems require optimizing more than one objective function at the same time. These functions are usually in conflict with each other so there is no single solution which can optimize them all simultaneously. The complexity of many of these optimization problem has led to the use of metaheuristics algorithms for helping decision makers to find optimal trade-off solutions. Nature-inspired metaheuristics are by far the most popular algorithms for multi-objective optimization metaheuristics in current use. This special session aims at providing a forum for presenting and discussing on the latest advances in this interesting field of research. Abstracts covering theory, practice, and applications of nature-inspired metaheuristics for solving multi-objective optimization problems are solicited.
