Abstract

The identification of important planning subgoals, referred to as landmarks, has been shown to be useful in speeding up plan generation in a number of different planning architec- tures [8]. Here, we report on work in progress to extend some features of this domain analysis using landmarks. In particular we consider: the extraction of resource abstracted landmarks; and the identification of landmark repetition along with a count of the minimum number of times a landmark will need to be repeated. We illustrate our ideas with an example from a benchmark domain and consider ways in which this information could be exploited at plan time.
