AI Magazine 

The first feature is a special section of competition reports, edited by Sven Koenig and Robert Morris. In this issue the section highlights results from three competitions: the Seventh International Planning Competition, the International SAT Solver Competitions, and the Trading Agent Competition. Recurring competitions play an important role in the progress of many AI areas, and Koenig and Morris hope to make coverage of such competitions -- including how the competitions illuminate the state of the art -- an ongoing section in AI Magazine. I thank them for initiating this exciting feature and encourage future submissions. Please see the solicitation and guidelines included in this issue on page 10.
