This book constitutes the joint refereed proceedings of six workshops, EvoWorkshops 2003, held together with EuroGP 2003 in Essex, UK in April 2003.

The 63 revised full papers presented were carefully reviewed and selected from a total of 109 submissions. In accordance with the six workshops covered, the papers are organized in topical sections on bioinformatics, combinatorial optimization, image analysis and signal processing, evolutionary music and art, evolutionary robotics, and scheduling and timetabling.

Research in hybrid metaheuristics is now established as a reference ?eld in the areas of optimization and problem solving. Hybrid metaheuristics have a strong impactonapplicationsbecausethey providee?cientandpowerfulproblemso- ing techniques for optimization problems in industry. Furthermore, the related interdisciplinary research community provides a fertile environment where in- vative techniques are presented and discussed. The International Workshop on Hybrid Metaheuristics pursues the direction of combining application-oriented and foundational research. This is dem- strated by the...
