General Information

The 5th Workshop on Algorithm Engineering and Experiments (ALENEX 03), will be held in Baltimore, Maryland, on January 11, 2003 at the Hyatt Regency Baltimore on the Inner Harbor.

The aim of the annual ALENEX workshop is to provide a forum for the presentation of original research in the implementation and experimental evaluation of algorithms and data structures. We invite submissions that present significant case studies in experimental analysis (such studies may tighten, extend, or otherwise improve current theoretical results) or in the implementation, testing, and evaluation of algorithms for realistic environments and scenarios, including specific applied areas (such as databases, networks, operations research, computational biology and physics, computational geometry, and the World Wide Web) that present unique challenges in their underlying algorithmic problems. We also invite submissions that address methodological issues and standards in the context of empirical research on algorithms and data structures.

The scientific program will include invited talks, contributed research papers, and ample time for discussion and debate of topics in this rapidly evolving research area. A proceedings will be published, and a special issue of the ACM Journal of Experimental Algorithmics will feature invited contributions from the workshop.

This workshop is co-located with the 13th Annual ACM-SIAM Symposium on Discrete Algorithms (SODA03), and will take place the day preceding that conference. A paper that has been reviewed and accepted for presentation at SODA is not eligible for submission to ALENEX. We recognize, however that some research projects spawn multiple papers that elaborate on different aspects of the work and are willing to respond to inquiries about overlapping papers.

The ALENEX workshop is supported by SIAM (Society for Industrial and Applied Mathematics), and SIGACT (ACM Special Interest Group on Algorithms and Computation Theory).


Authors are invited to submit 10-page extended abstracts by 5:00 PM EDT, September 23, 2002 and must use the SIGACT electronic submission server.

Notification of acceptance or rejection will be sent by the end of November, 2002. The deadline for receipt of papers in final version will be included in the acceptance notification. Presenters must have submitted the final versions of their papers in order to be able to present them at the workshop.
