This section of the newsletter contains a collection of summaries of current research on planning. Although the number of projects described is modest, the variety of topics and institutions represented illustrates a healthy and growing interest in this area. In contrast with early research, much of which dealt with "blocks-world" problems, a significant portion of the research described here is confronting so-called "real-world" problems, such as planning with incomplete information, planning with large numbers of constraints, and planning in a non-cooperative environment. The role of planning in communication is also an important topic. Furthermore, in addition to covering a broad range of topics, the research covers the spectrum from quite theoretical to fairly practical.
