Guessing and Games [From the Editor]

Having recently returned from the 2010 American Control Conference (ACC) in Baltimore, I marvel at how thousands of new papers emerge every few months from our research community. Each paper advances the state of the art in systems and control, and the cumulative effect is to move the field forward. Admittedly, not every conference or journal paper has a major impact on the field. But each paper is part of a process of developing and testing new ideas and techniques. Just as a musician practices etudes to build proficiency, each paper and presentation allows us to hone our skills in performing research and in communicating our results to one another.
