The WEA Workshops are intended to be an international forum for researchers in the area of design, analysis, and experimental evaluation and engineering of algorithms, as well as in various aspects of computational optimization and its applications.

The three preceding Workshops in this series were held in
Riga (2001),
Monte Verita (2003, http://www.idsia.ch/wea2003/) and
Rio de Janeiro (2004, http://wea2004.inf.puc-rio.br/).

The WEA 2005 Workshop is sponsored by the European Association for Theoretical Computer Science (EATCS) and the EU IST/FET R&D Projects FLAGS ("Foundational Aspects of Global Computing Systems") and DELIS ("Dynamically Evolving Large-scale Information Systems") and the Research Academic Computer Technology Institute (RACTI).

The Proceedings of WEA 2005 will be published in the Series Lecture Notes in Computer Science (LNCS), by Springer Verlag.

Selected papers from WEA 2005 will be considered for a Special Issue of the ACM Journal of Experimental Algorithmics (JEA, http://www.jea.acm.org/).

Authors are invited to submit manuscripts reporting original unpublished research and recent developments in the topics related to the Workshop. Simultaneous submission to conferences with published proceedings is not allowed. Papers should not exceed twelve (12) SINGLE-spaced pages of text, using at least 11 point size type on 8.5 x 11 inch pages, including references, figures, tables, etc. It is highly recommended to use the Springer LNCS LATEX style format (http://www.springer.de/comp/lncs/authors.html). Additional material may be added at a clearly marked Appendix to be read at the discretion of the Program Committee Members.

Authors must submit their papers electronically via EDAS (http://edas.info/).

All papers will be peer reviewed and comments will be provided to the authors.

Authors need to make sure that for each accepted paper at least one author will attend the Workshop.

• Submission Deadline: Extended - January 20, 2005, 11pm GMT (firm)
• Author Notification: February 28, 2005
• Final Manuscript Due: March 14, 2005
