Planning and learning research has been progressing in parallel over the past several years, but very few research projects have bridged the two areas. However, there is a great deal of benefit from their interaction, especially when they are concerned with real applications. As the complexity of planning problems increases, it becomes of particular interest to identify learning opportunities in order to automate the acquisition of a planner’s knowledge in new applications. At the same time, planning problems are a useful testbed and a source of challenges for learning research. The goal of this symposium is to discuss the implications of practical planning applications on both learning and planning research.
